With a subtle look and ample venting, this helmet will steer you through the wildest terrain with comfort and ease. 360Adeg K2DIALED(TM) FIT SYSTEM: The 360Adeg K2Dialed(TM) Fit System is an evolution of the K2Dialed(TM) Fit System, delivering unparalleled comfort around your entire head. An intricate web design results in 360 degrees of even pressure distribution for a secure and snug fit that you customize with the twist of a dial. BIKE CERTIFIED: Certified by North American bicycle helmet safety standard and European bicycle and skateboard helmet safety standard. MAGNA SNAP: Magnetic retention clip that easily flips up and over the goggle strap for a secure hold that you don't have to fumble for. IN-MOLD CONSTRUCTION: In-Mold is the premium construction for ultra-lightweight performance and is characterized by an EPS liner that is molded directly to a lightweight poly-carbonate (PC) shell. The result is a construction so light you'll forget it's even there. CONVERTIBLE FULL WRAP LINER: Same coverage as a full-wrap but easily pops out, leaving the fit system and minimal padding to accommodate warm days and wearing a thin beanie under the helmet. PASSIVE CHANNEL VENTING: Channels on the inside surface of the EPS direct air-flow between your head and the helmet, removing moisture and excess heat for all day comfort.
