From frames and wheels to helmets and water bottles, aerodynamics have changed cycling. Kask's Infinity helmet gives you the edge with an aerodynamic advantage and ride-all-day comfort, too. When you need more venting, the Infinity has a special feature—the front panel slides up revealing a row of vents to cool you off. And, Kask's OctoFit adjustment system uses floating cradle contact points and gel pads for an unparalleled fit. The Infinity is finished out with an eco-leather chinstrap that's comfortable and easy to clean, and removable and washable CoolMax padding.
