Kevin Fitzgerald wrote a review of Mammut Skywalker 2 Climbing Helmet on June 13, 2012
I've been using this helmet for almost two years now. The fit as everyone says is a little high on the noggin, but it's great when your ice climbing and you can tilt it down some and it'll still protect you skull while looking up. Gotta be able to dodge those ice chunks!
Someone had said the padding on the inside could get a little funky, I personally haven't had that problem. Overall, for a helmet that I take out almost every weekend, I'm seriously impressed that it's still in great shape!
