Hit up Ski & Sports Santa Monica man, they're pretty legit. It used to be called Doc's Ski Haus, been there for decades I'm pretty sure. This year though for some reason they sold the name or something so now they are called Ski & Sports and down the street there is a new store called Doc's Ski Haus that has nothing to do with it, its sort of confusing. If you are looking for them they are the google link that links to facebook instead of an actual website.
They actually only carry ski gear too, they don't even sell snowboards I'm pretty sure. Which is amazing because in the part of LA I live in there are like 10 places to buy snowboards and the only place that sells skis is Sport Chalet. They only carry Spyder outerwear though which is pretty lame.
