I think as a general rule, snowboard company garb is crap. BUT… I have a pair of Volcom Gore-tex pants and they're awesome! I think their cheap stuff kinda blows, but the high end stuff can definitely take a good beating. Ive put about 150+ days on the pants, teleing (which usually means they get the shit cut out of them) and theyre still going strong.
This is one of the prime bonuses of getting Gore-Tex gear. They won't let just anyone use the Gore-Tex hang tag and name. So the gear actually has to be approved by Gore-Tex.
So yes most snowboard outdoor apparel is crap…but if it's a Gore-Tex item you will likely fair much better.
