Right on. I might have to give them a shot. I found their bc bib for $150. I've seen a handful of reviews on their jackets (Always positive) but never on the pants.
I've owned several Westbeach garments in the past (still have a few in my spare closet I think) and they're adequate quality. We're not talking Patagonia/Arctyrex/Burton AK quality, but pretty much good enough for any mortal person to go recreational snowboarding.
They are having a MASSIVE clearance on their website right now so it would be a great time to pick up a more expensive item you have your eye on - you just wont' have the full selection of sizes and/or colorway's because they generally don't put the most popular ones on sale.
I just picked up a pair of pants and jacket from them in the fall, and got to test them out finally a couple weeks ago. So far, I'm loving them. Im not a hardcore rider by anymeans, so I can't comment with that respect, but for the warmth and waterproof quality, they have been pretty good so far. I'd buy the brand again.
