-Great fit, doesn't move around especially when locked down my goggle strap
-Great ventilation, open up or cover up vents on demand
-Ultra-light, can barely feel it on your head. Advertised as the lightest on the market and I don't disagree.
-Great goggle integration, at least with Smith goggles, Oakley Crowbars, or Spy Platoons.
-Warm, no need for a beanie, especially with the included ear pads
-Great protection, can withstand a head hit on ice at fairly moderate speed, from experience
-Expensive, but you get what you pay for
-Ear pads jams in-ear headphones straight into the ear canal, painful but helps seal audio better
It's the helmet that I currently use, and will continue to use until something lighter comes along.
