hey man i wear a set of that stuff now because if i do any more nerve damage to my shoulder i'ma loose function in my right arm. so the only way i can avoid being paralized is to tkae some precautions, and i'm not gonna give up skiing over it you know?
i find that it really doesnt restrict any movement, it makes you look alot bigger and you look kinda goofy with such a huge upper body... you can pretty much zip off any of the parts that get annoying, but i find that the back thing is pretty nice on really icy days, esp if you eat shit really hard landing switch, you just slide and slide and slide hahaha theres alot less bumps and bruises which is nice, and it doesnt really get in the way... but try it out, zip off the stuff that bugs you and if you dont like it dont wear it.
