I have used these
($45) Cabela's gloves for 4 years and they just wore out so I ordered these
($55) just yesterday. They have a 1 cent shipping deal until Feb 13th using the code 22PENNY.
The gloves are gore-tex (waterproof) and have 150 gram thinsulate insulation (means nothing to me too), but they are super warm. I shook a guys hand in line for the lift the other day and he was surprised at how warm my had was. They're not snowboard specific, but they are warm and waterproof and have held up well for me. The leather in the fingertips on my left hand wore through this year and I couldn't figure out why (the right side was still fine,) and then I realized it's from cleaning snow out of my binding before I strap in. (I ride goofy.)
