Supposedly super thin for great dexterity, completely waterproof, and super warm.

at them I wouldn't consider wearing them snowboarding. If a glove has a good liner and proper fitting insulation, taking the outer off to zip up a jacket, adjust music, etc is not a problem. They have other gloves, but I get sketchy when I read about how great/warm/blah that glove is supposed to be when they have goretex gloves on their website too.
