Aero helmets like the Infinity have become a staple of the pro tours, seeing use by Team Sky, Katusha and others. This is more than just a trend, drag can be reduced by up to 14% just by making the move to an aerodynamically optimized helmet. How does one achieve that much savings? Often by removing the large vents and scoops that keep you cool on those long summer rides.

Kask decided that they didn’t want to sacrifice comfort in the pursuit of energy savings. The smooth subtle shape still houses 11 vents while retaining aerodynamic advantage. The genius of the Infinity lies in the 3 large front vents: close them via the switch located on the top of the helmet and bank up some savings.

Of course, this helmet’s sleek aero shape wouldn’t mean anything if it didn’t come with a host of safety features. The polycarbonate outer layer of the helmet is bonded directly to the EPS polystyrene core for better shock absorption with a lighter weight. If a crash involved multiple impacts, Kask’s Frame technology keeps things together with its web-like inner lattice of kevlar-like material, adding both durability and rigidity. In the case of an impact, this frame keeps the helmet from fragmenting. And of course, this helmet wouldn’t bear Kask’s name if it didn’t offer outstanding comfort. From the eco-leather straps, to the plush antimicrobial CoolMax pads, to the Micro Dial retention system for precise and quick adjustments.
