Pros & Cons

Reasons to buy:

User Reviews

  • Goggle retention system integrates well with adjustable vents.
  • Users loved the snug, warm fit of the helmet, even before making any BOA adjustments.
  • Great balance of style, safety, and function.
  • When closed, the 22 vents really don’t let in any air.
  • One of the safest helmets out there.

Expert Reviews

  • Helmet lining is simultaneously warm and wicks sweat away to keep head dry.
  • BOA fit adjustment system personalizes fit and is easy to use with gloves on.
  • Nice variety of understated colors available.
  • Tight helmet seal with Julbo, Zeal, Giro, Native Eyewear, Smith, Oakley, and POC goggles.
  • Short visor cuts down on wind slippage through goggles, which may be helpful for those that tend to tear up on cold descents.
  • 2 slider mechanisms effectively lock vents closed for colder days, but with 22 vents there is ample ventilation for warmer days too.
  • Buckle and strap system can be manipulated with one hand.
  • Bombshell earpads are removable for warmer days.
  • When worn without a beanie or buff underneath, the helmet’s ear cups are fairly warm and very comfortable.

Reasons NOT to buy:

User Reviews

Expert Reviews
