i have two helmets. a boeri cross (full face) and a just normal helmet, not sure which one. i wear the full face basically full time now. i don't spend much time every in the park, and when we build jump it is usually OB, i basically just go in the park when i'm skiing by it. this spring when we jump, i probably won't wear it just becuase it can be really hot if your hiking. i got it after get to concussions within a month last year off bouchted cliff drops envolving once a knee to the face and once a rock to the face. i don't think it impairs your vision at all. this one is the first made for skiing though. the biggest thing is to make sure you get a pair of goggles that fit your helemt and head perfect. i've taken a couple of cartwheel types of falls this year and it never caught to snow, but that was in pow/crud. haven't seen what happens on hardpack. i like it. it comfortable, warm, blocks wind, has already prevented me from hurting myself when i hit a tree branch. plus, i got me pro form for like $75 down from $260, so it seem worth it. i'll recommended it to anyone who like cliff drops or exposed line with the possibilty of cartwheeling over exposed rocks and the liking, which are my favorate thing to do, but those who just spend all day hiking to park, or if you live in the midwest it is just extra weight.
