Giro's Xar Helmet represents the best blend of value, protection, and ventilation for a mountain bike helmet. It's a bit more subs...tantial than, say, the road-specific Atmos II, but that's because its job is different. It's made to provide more coverage to the sides and back of your head while also resisting the every, branch-bumping nature of trail riding. A lightweight, barely-there road helmet is designed to protect against a single, serious impact -- like an airbag. The Xar is more like the constant support of a seatbelt. The Xar begins life as a roll cage made from DuPont Nylon, which provides a structural skeleton for the impact-absorbing EPS foam body. This keeps the helmet from shattering under impact. The In-Mold construction process fuses the EPS layer to the outer, polycarbonate one to reinforce the helmet -- especially the spots around the vents and ribs. It makes them lighter, more durable, and better ventilated than helmets with shells that are glued to the liner. The Xar's 17 Wind Tunnel vents and internal channeling shuttle air across your head while pulling heat up, up, and away. The P. O. V. visor increases comfort in a different way, by deflecting the sun, rain, and the odd twig or errant pebble kicked up by your riding buddies. The visor's internal clutch system allows for 15 degrees of vertical adjustment achieved by a very precise and technical quick whack of the hand. Its removal is just as easy and tool-free. The Roc Loc 5 fit system uses a ratcheting dial to adjust the helmet's fit. Read More

Funny how what looked like a step back turned out to be a step up. Giro's new Prolight Helmet debuted on the stage to Arcalis in t...he 2009 Tour de France. It looked odd, as if Giro had given their riders a retro helmet for an important mountain stage. We were right and wrong at the same time. The Prolight shares a name with Giro's debut product, the Prolight, of 1985. But it represents all of Giro's knowledge in weight-saving helmet technology. The goal was to make a 200 gram helmet (and a medium weighs just that), a weight that is 2/3 of their marquee model, the Ionos. 200g is crazy light for a helmet. Even the old leather hairnets of the Merckx era would have trouble crossing this barrier. Giro did a lot of rethinking with this helmet. The changes aren't just the weight, though reducing grams was the point of just about every change. The Roc Loc SL, Giro's secondary retention system, is a completely new design. The obvious is that it saves 20g of weight savings compared to the Roc Loc 4. Elastic and non-elastic segments keep the helmet anchored to your head with a minimum of weight and fuss. There are three snap baskets at the forward ends of the Roc Loc SL that allow you to adjust how firmly it grabs your head. Giro also scrutinized the helmet straps. Their usual nylon strap material wasn't light enough, so they searched the world and found some thin Italian nylon strap material. It feels ribbon-thin, yet it's strong enough to survive impacts without ripping. The strap material saves 14g. The adjusting Tri-Loc buckles where the helmet straps join were also eliminated. Too heavy. The buckles are now no longer buckles but fixed points. As in, they don't adjust. But this shouldn't result in any worry that the fixed points will result in a helmet position that won't fit with your head. They studied countless heads and determined a position that works with most. Back to our memory of the Prolight. The vents were smaller. And the vents on the new Prolight are sma... Read More

Ready for casual or aggressive trail riding, the Giro Xara Women's Helmet balances ventilation, weight, and durability to keep you... cool and comfortable. The Xara gets the same expert engineering found in Giro's top-line helmets -- that means it has the same In-Mold process that make Giro helmets some of the strongest and lightest on the market. The In-Mold construction process fuses the outer shell to a EPS foam liner. This process enhances the effectiveness of both parts. In fact, the fusion process actually reinforces those formerly vulnerable spots around the vents and ribs. It makes them lighter, more durable, and better ventilated than helmets with shells that are glued to the liner. This process safely creates 17 Wind Tunnel vents with internal channeling. The Xara also gets the benefit of a P. O. V. visor to deflect the sun, rain, and twigs. The visor has a patented internal clutch system that allows for 15 degrees of vertical adjustment without the need for any tools; just give it a quick whack with your hand. And, if you'd rather not have it on at all, you can easily remove it without tools. Giro's development of the Roc Loc 5 Fit System makes it possible to micro-adjust your helmet on the fly, with just one hand. Though other helmet manufacturers have similar adjustability options, none of them even come close to the weight savings that the Roc Loc system offers: it is almost 40% lighter than comparable systems. But, that's only on benefit of Roc Loc, it's also adjustable vertically as well as horizontally for an excellent fit. The Giro Xara Women's Helmet comes in Small, Medium and Large. It is available in Matte Black, Matte Titanium, and Pearl White. Read More

The Giro Cipher Helmet was designed to fill the void between freeride helmets and enduro helmets. The former is typically a little... too heavy for the latter, while the latter needs more breathability than the former. The Cipher is strong enough for both but far lighter than you'd expect, making it a great hybrid, and then some. The Cipher's shell is molded with channeled ventilation at the brow line to get the most airflow without any sacrifice to structural integrity. On the interior, plush padding is anti-static and antimicrobial, and furthering that, they can be removed to wash. For visibility, the visor is adjustable without tools, and custom-injected gaskets around the port ensure excellent field of vision.

So much scienc...e is focusing on aerodynamics these days, it's no wonder that the humble helmet -- responsible for surprisingly large amounts of drag on your bike -- has been thoroughly revised over the last few seasons to become more slippery. The results speak for themselves -- witness their popularity in the pro peloton, and the success of Giro's top-of-the-line Synthe aero helmet. Of course, we can't all afford the seriously fancy stuff, so Giro made fancy stuff that's more affordable for the Average Jane, and here we have the Giro Saga Helmet.

For over a decade, the Giro Advantage 2 has proven to be the pinnacle of aerodynamic performance, with a rich history of wins at t...he pro level. Giro relies on wind tunnel data to improve even the smallest of details to shave seconds off your times. Though the smooth, teardrop design of the helmet is what gives you the biggest advantage, the superb fit and ventilation are what continue to make it a top choice year after year. The latest iteration of Advantage 2 helmet uses the same Super Fit Engineering that Giro has created using 'human scale factor' data they have collected over the past 20 years. In short, the three sizes of the Advantage 2. combined with the Roc Loc 5 retention system, make it look and feel like it was custom made for your head. Custom fit might sound like a pretty big campaign promise, but Giro's development of their Roc Loc 5 Fit System has made it possible to make those micro adjustments. With the Roc Loc system, you can tune the fit tension as well as the fore and aft tilt of the helmet with one hand. Though other helmet manufacturers have similar adjustability systems, none of them can compete with the Roc Loc system in terms of weight: it's almost 40% lighter than comparable systems. In a helmet style not typically known for being light, this is a significant reduction. Remember those days in the early 2000s when the UCI made it so that aero helmets had to have the same EPS safety foam as the regular road helmets? For those of you who never missed a Lance Chronicle, you'll remember the Giro designers going through all sorts of hell to get an aero helmet ready that would be acceptable to both the UCI and Lance. The Advantage 2 is the love child of that relationship. Through the use of In-Mold construction, the durable but light outer shell is permanently fused to the impact absorbing EPS foam liner. This process enhances the effectiveness of both parts. In fact, the fusion process actually reinforces those formerly vulnerable spots around... Read More

Aerodynamic road helmets became something of a trend over the last couple of years, with Giro's Air Attack Shield Helmet leading t...he way. It doesn't lead from the wind tunnel, though, which is where so many of these helmets get developed and tested. It leads from the velodrome, where the pros from BMC Racing recorded times that were 56 seconds faster over 40 kilometers. It leads from Kona atop Cave, the world champion from Great Britain. Now, it's leading into 2015 with the same design that makes it a favorite for pros across so many disciplines. The helmet features the same front area as Giro's Selector time trial helmet, with the back -- or rather, the lack thereof -- really setting the Air Attack apart. Wind tunnel testing proved that passing air still thinks it's moving around a long tail, when, in fact, the excess material no longer exists. In addition to now having roughly the same minimal drag (only 11% more) than the Selector, the Air Attack provides a drastic increase in weight savings, 264g versus the Selector's 430g. The low-vent design initially inspired fears of 100 degree Fahrenheit days with a stifling bowl on our heads. Giro researched solutions to this concern with something it calls the Therminator, a head-shaped object equipped with sensors. The Therminator went into the wind tunnel and data came out, showing Giro where vents work, where they don't, and providing a map for ideal ventilation with as few vents as possible. Giro also found that as air hits the rider, there is a very high pressure zone right at the forehead. In response, the Air Attack's new fit system, known as Roc Loc Air, suspends the rider's head off of the EPS, allowing air entered in that front three millimeter portion of the helmet to flow over the top of the head and out the large, strategically placed back channels. Amazingly, the Air Attack boasts 97% of the cooling efficiency found in the barely-there minimalist Aeon helmet with an 11% boost in aerodynamics. The poly... Read More

After years of watching a wide range of athletes buy its beloved Atmos road helmet for off-road racing, Giro decided to go ahead a...nd design a mountain-ready version of the new Atmos II, and so created the Giro Fathom Helmet. A structural clone of the Atmos II, boasting the new Thermoformed SL Roll Cage, the Fathom gets its own styling and a removable visor, making it just that much more ready to hit the trail. The SL Roll Cage is the skeleton that gives form to the helmet's EPS liner. It keeps the helmet together under impact, acting like a second shell to maintain the helmet's structural integrity and disperse impact. The added strength also means that Giro can add negative space to the Atmos II without sacrificing safety, so it's more ventilated and lighter than its predecessor. The Atmos II still takes advantage of Giro's In-Mold Composite reinforcement, which permanently fuses the outer shell and SL Roll Cage to the EPS foam liner to enhance the effectiveness of all three. In an age of mass production, Giro's Roc Loc 5 Fit System makes the Atmos II fit like a custom one-off. You can custom tune the fit tension as well as the fore-aft tilt of the helmet in seconds with one hand. Though other helmet manufacturers have similar adjustability options, none of them even come close to the weight savings that the Roc Loc system offers; it's almost 40% lighter than comparable systems. Keeping your head cool during even the hottest, most critical road races is something that Giro has focused a great deal of attention on. Giro helmets are developed with a proprietary Wind Tunnel Ventilation System that combines 26 vents in the shell with exhaust channels within the belly of the helmet leading to the rear. Fresh, cool air from the front is strategically channeled around the head to help evaporate the sweat before exiting through the rear exhaust openings. It's a natural cooling system that you'll appreciate every ride. Read More

We've come a long way from the Giro 'ice chest' aero helmet that Greg Lemond wore when he rode to a last stage upset of Laurent Fi...gnon in the '89 Tour. In a similar twist of the general classification, Levi Leipheimer overcame a two minute deficit coming into a last stage time trial to leapfrog up the standings to win his first Tour de Suisse in 2011. He did this while wearing the Giro Selector Helmet. It's the successor to the longstanding benchmark for aero helmets, the Giro Advantage. As you might expect, Giro has used wind tunnel data to sculpt the new helmet in order to make it slicker and faster than the Advantage. And for most riders, a sleek helmet will do as much, or more, for lessening the overall drag coefficient as any other static change that you make to your bike or personal gear. The Selector has two significant upgrades that not only make it your best choice for aerodynamics, but that necessitate necessary changes towards comfort. The first thing that you'll notice is the eye shield -- its purpose is to enhance the aero properties of the helmet by smoothing the leading surface. A more subtle benefit that you'll notice is a quieter experience as you ride. If nothing else, we've found that this perception of less wind noise acts as a placebo -- less noise, less resistance, more speed, etc.. However, the lens is removable if you prefer to wear sunglasses. The lens also has two vents, located on either side of the center line at the top edge. They minimize the chance for fogging on humid days, and they duct a sizeable volume of cooling air to flow over the head and out the twin exhaust ports in the tail of the helmet. The back of the helmet is where you'll find the other big changes. Where the Advantage had a tail that was open on the underside, the Selector Helmet is closed, more akin to a belly pan on an F1 car.

The Giro Aeon Helmet proves that lightweight and highly ventilating aren't synonymous with fragility. Despite its claimed weight o...f 218 grams -- around 45% lighter than most of its competitors -- and 24 capacious Wind Tunnel vents, the Aeon is CPSC certified, so there's no compromising safety for a light helmet and a cool head. With such an effective recipe for cool-headed safety, the Aeon remains largely unchanged for 2015. The Aeon sees the return of Giro's Roc Loc 5 retention system. The Roc Loc 5's indexed Micro Dial lets you adjust the tension with a two-fingered twist, and the three position bracket allows 15mm of vertical adjustment in the retention basket. Even in an age of mass production, Giro's Roc Loc 5 Fit System makes the Aeon fit like a custom one-off. While other helmet manufacturers have similar adjustability options, none of them even come close to the weight savings that the Roc Loc system offers; it's almost 40% lighter than comparable systems. The Aeon uses in-mold construction to fuse the foam liner to the abrasion and puncture resistant polycarbonate shell as other Giro helmets. However, Giro uses a low-density EPS liner for the Aeon that performs the same important task of absorbing impacts, yet it's 15% lighter than the foam they used previously. These weight savings are further complemented by the Thermoformed SL Roll Cage, which acts like a second shell to maintain the helmet's structural integrity and disperse impact. The added strength also means that Giro can add negative space to the Aeon without sacrificing safety, so it's more ventilated and lighter than its predecessor. Occasionally, it's easy to imagine that helmet designers simply fill every possible space with vents and gaps designed to look aerodynamic or cooling or both. Not so with Giro, whose proprietary Wind Tunnel Ventilation System combines 24 vents in the shell with internal exhaust channels. Fresh, cool air from the front is strategically guided around the head to he... Read More

In the never-ending quest for helmet lightness, one fact makes us rest easy: Even the most feathery helmets must pass the CPSC saf...ety standard for impact resistance. If, for example, you've ever picked up a Giro Prolight or Aeon helmets, you know why this is a concern. It seems impossible that a near-weightless thing like these helmets offers adequate protection. Amazingly, though, they pass the CPSC testing just fine. The Prolight tips the scale at 200 grams, nearly 50% lighter than most alternatives in its $200 price range. Its lightness comes thanks to several factors, the most noticeable of which is its lack of fit adjustment hardware. Its Roc Loc SL is made from elastic and offers none of the fine-tuning of other Roc Loc models. Furthermore, the strap buckles beneath your ears are fixed and non-adjustable on the Prolight. And while this might seem like a reasonable price to pay for lightness, if you ever choose to wear a cycling cap or winter hat beneath your helmet, the resulting tightness around your head is a bummer. Enter the Giro Aeon. With the Aeon, Giro's goal is to offer the next generation of superlight helmet design. The Aeon marries the breathtaking lightness of the Prolight and the fabulous ventilation and adjustability of the Ionos. At 218 grams (size Medium), the Aeon is in the same weight class as the Prolight, but it offers far more fine-tunability to the fit. It comes with Giro's all-new Roc Loc 5 retention system. For starters, the indexed Micro Dial lets you adjust the tension with a two fingered twist. And its three position bracket allows 15mm of vertical adjustment in the retention basket -- enough to fit any head shape comfortably. In another improvement over the Prolight, you get clever strap management. The retention basket has strap holders to ensure that they'll be right where you want them by the time the helmet falls into place on your head. The Aeon uses in-mold construction to fuse the foam liner to the abrasion and punctu... Read More

How much do we love the Giro Atmos Helmet? So much that it's been a permanent fixture in our cycling closets since it first appear...ed on the scene. Sure, we've flirted with some new, good-looking lids, but we've always come back to our true love, the Atmos. The Atmos was the first helmet that ever looked amazing, while also saving our lives. It had tons of air channels, it was lightweight, and it was seriously durable -- this was still back when most helmets looked awful and weighed heavily on the head. And today, it still looks so cool, and works so well, that it's the most popular helmet that we've ever sold. The Atmos was so groundbreaking because it was the first helmet that made use of Giro's In-Mold Composite reinforcement. Through the use of this construction process, the outer shell has been permanently fused to the impact-absorbing, EPS foam liner. This process enhances the effectiveness of both parts. In fact, the fusion process actually reinforces the formerly vulnerable spots around the vents and ribs. It results in a lighter, more durable, and better-ventilated helmet. The Roll Cage internal reinforcement gives the added protection that you'll be glad to have next time someone takes you down in the final corner of a criterium. The amazing comfort that the Atmos offers has been one of the main reasons for its longevity. Giro has taken over 20 years of helmet design to establish its proprietary, Super Fit Engineering. This means that Giro has created the helmet in three sizes based on 'human scale factors' data that have amassed throughout its history of handcrafting helmets. The helmets are intended to fit snugly and securely, while still accommodating the vast majority of head sizes. Giro's development of its Roc Loc 5 Fit System makes those micro-adjustments possible. With the Roc Loc system, you can custom tune the fit tension as well as the fore-aft tilt of the helmet in seconds with one hand. Though other helmet manufacturers have similar adjus... Read More

For over a decade, the Giro Advantage 2 has proven to be the pinnacle of aerodynamic performance, with a rich history of wins at t...he pro level. Giro relies on wind tunnel data to improve even the smallest of details to shave seconds off your times. Though the smooth, teardrop design of the helmet is what gives you the biggest advantage, the superb fit and ventilation are what continue to make it a top choice year after year. The latest iteration of Advantage 2 helmet uses the same Super Fit Engineering that Giro has created using 'human scale factor' data they have collected over the past 20 years. In short, the three sizes of the Advantage 2. combined with the Roc Loc 5 retention system, make it look and feel like it was custom made for your head. Custom fit might sound like a pretty big campaign promise, but Giro's development of their Roc Loc 5 Fit System has made it possible to make those micro adjustments. With the Roc Loc system, you can tune the fit tension as well as the fore and aft tilt of the helmet with one hand. Though other helmet manufacturers have similar adjustability systems, none of them can compete with the Roc Loc system in terms of weight: it's almost 40% lighter than comparable systems. In a helmet style not typically known for being light, this is a significant reduction. Remember those days in the early 2000s when the UCI made it so that aero helmets had to have the same EPS safety foam as the regular road helmets? For those of you who never missed a Lance Chronicle, you'll remember the Giro designers going through all sorts of hell to get an aero helmet ready that would be acceptable to both the UCI and Lance. The Advantage 2 is the love child of that relationship. Through the use of In-Mold construction, the durable but light outer shell is permanently fused to the impact absorbing EPS foam liner. This process enhances the effectiveness of both parts. In fact, the fusion process actually reinforces those formerly vulnerable spots around... Read More

We've come a long way from the Giro 'ice chest' aero helmet that Greg Lemond wore when he rode to a last stage upset of Laurent Fi...gnon in the '89 Tour. In a similar twist of the general classification, Levi Leipheimer overcame a two minute deficit coming into a last stage time trial to leapfrog up the standings to win his first Tour de Suisse in 2011. He did this while wearing the Giro Selector Helmet. It's the successor to the longstanding benchmark for aero helmets, the Giro Advantage. As you might expect, Giro has used wind tunnel data to sculpt the new helmet in order to make it slicker and faster than the Advantage. And for most riders, a sleek helmet will do as much, or more, for lessening the overall drag coefficient as any other static change that you make to your bike or personal gear. The Selector has two significant upgrades that not only make it your best choice for aerodynamics, but that necessitate necessary changes towards comfort. The first thing that you'll notice is the eye shield -- its purpose is to enhance the aero properties of the helmet by smoothing the leading surface. A more subtle benefit that you'll notice is a quieter experience as you ride. If nothing else, we've found that this perception of less wind noise acts as a placebo -- less noise, less resistance, more speed, etc.. However, the lens is removable if you prefer to wear sunglasses. The lens also has two vents, located on either side of the center line at the top edge. They minimize the chance for fogging on humid days, and they duct a sizeable volume of cooling air to flow over the head and out the twin exhaust ports in the tail of the helmet. The back of the helmet is where you'll find the other big changes. Where the Advantage had a tail that was open on the underside, the Selector Helmet is closed, more akin to a belly pan on an F1 car. The helmet comes with two versions of the lower cover, one that extends down 10mm and another that extends 45mm. This design promotes s... Read More

In the never-ending quest for helmet lightness, one fact makes us rest easy: Even the most feathery helmets must pass the CPSC saf...ety standard for impact resistance. If, for example, you've ever picked up a Giro Prolight or Aeon helmets, you know why this is a concern. It seems impossible that a near-weightless thing like these helmets offers adequate protection. Amazingly, though, they pass the CPSC testing just fine. The Prolight tips the scale at 200 grams, nearly 50% lighter than most alternatives in its $200 price range. Its lightness comes thanks to several factors, the most noticeable of which is its lack of fit adjustment hardware. Its Roc Loc SL is made from elastic and offers none of the fine-tuning of other Roc Loc models. Furthermore, the strap buckles beneath your ears are fixed and non-adjustable on the Prolight. And while this might seem like a reasonable price to pay for lightness, if you ever choose to wear a cycling cap or winter hat beneath your helmet, the resulting tightness around your head is a bummer.

The Giro Cipher Helmet was designed to fill the void between freeride helmets and enduro helmets. The former is typically a little... too heavy for the latter, while the latter needs more breathability than the former. The Cipher is strong enough for both but far lighter than you'd expect, making it a great hybrid, and then some. The Cipher's shell is molded with channeled ventilation at the brow line to get the most airflow without any sacrifice to structural integrity. On the interior, plush padding is anti-static and antimicrobial, and furthering that, they can be removed to wash. For visibility, the visor is adjustable without tools, and custom-injected gaskets around the port ensure excellent field of vision. On the tech side of things, Giro's made sure the Cipher's ready for your needs. This includes an integrated P. O. V. camera mount, plus built-in TuneUps speaker pockets for ear buds. Read More

To us, the hallmark of a Giro design are its three central vents. And, not coincidentally, you'll find this feature on the Giro Sa...ros Helmet. It was originally part of the Prolight design, but nearly every subsequent helmet has revolved around the three prominent central holes. To us, this trident conveys stability and balance. And while Giro builds on older designs, it never adds baroque touches, instead opting for little practical flourishes. So, in this tradition, the Saros helmet hearkens to the long-gone days of the Eclipse, while moving forward into the contemporary. With the Saros, you receive trickle-down technology like the Roc Loc 5 --Giro's easiest to use and most comfortable retention system to date. Also used in Giro's top-of-the-line Aeon helmet, Roc Loc 5 adds more adjustability, while removing 40% of the weight from its prior iteration. So, what's different? For starters, the indexed Micro Dial on the back lets you adjust the tension to perfection with a two fingered twist. It's really that simple. Additionally, the Three Position Bracket allows 15mm of vertical adjustment in the retention basket -- enough to comfortably fit any head shape. But, what's comfort without ease of use? Giro facilitates quick donning of your casque with clever strap management. The retention basket has strap holders to ensure that they'll be right where you want them by the time the helmet falls into place. For protection (that is what a helmet does, right?), the Saros features an in-molded polycarbonate shell that, when combined with the expanded polystyrene liner, creates a structural skeleton that's abrasion-resistant for any high speed slides across the pavement. Giro has also ensured that it aids in the absorption of any direct high-speed impacts. And going a step even further, the Saros also has Giro's Roll Cage technology. Don't worry about looking for it -- you'll never see it. It's a net of tough nylon that's been molded into the foam liner of the helmet. Ba... Read More

The Giro Amare II women's helmet looks a lot like the original Amare, and that's because it is, but the big changes made for the s...equel are ones you can't see: the introduction of the Thermoformed SL Roll Cage. The SL Roll Cage is the skeleton that gives form to the helmet's EPS liner. It keeps the helmet together under impact, acting like a second shell to maintain the helmet's structural integrity and disperse impact. The added strength also means that Giro can add negative space to the Amare II without sacrificing safety, so it's more ventilated and lighter than its predecessor. The Amare II still takes advantage of Giro's In-Mold Composite reinforcement, which permanently fuses the outer shell and SL Roll Cage to the EPS foam liner to enhance the effectiveness of all three. In an age of mass production, Giro's Roc Loc 5 Fit System makes the Amare II fit like a custom one-off. You can custom tune the fit tension as well as the fore-aft tilt of the helmet in seconds with one hand. Though other helmet manufacturers have similar adjustability options, none of them even come close to the weight savings that the Roc Loc system offers; it's almost 40% lighter than comparable systems. Keeping your head cool during even the hottest, most critical road races is something that Giro has focused a great deal of attention on. Giro helmets are developed with a proprietary Wind Tunnel Ventilation System that combines 26 vents in the shell with exhaust channels within the belly of the helmet leading to the rear. Fresh, cool air from the front is strategically channeled around the head to help evaporate the sweat before exiting through the rear exhaust openings. It's a natural cooling system that you'll appreciate every ride. Read More
