I have the Mineral pants. I havent had a chance to ski in them yet, but they look like they are going to keep me VERY DRY. They have Schoeller which is essentially like a swedish version of GoreTex. Ran them under the sink for awhile and water beads off them and did not get even the slightest bit wet. (20k/20k)The only thing i am worried about is the durability. Very thin towards the bottom of the pants.
I would imagine the Mineral jacket is constructed the same. Its just a shell, so dont expect a lot of warmth. But I live in WA so it doesnt get too cold. (Rain). I had the EP bibs last year. Those got a little soggy towards the end of the season, but kept me very dry and warm since they are insulated.
