The Gordini Alp Pro Mitten is a down ski mitten with a rugged WaxHide leather shell, a leather the brand treats for wear resistance, over a waterproof, windproof, breathable AquaBloc insert that lets moisture escape. The down insulation meets Responsible Down Standard guidelines. What Our Gearhead(R) Experts Are Saying:"The neoprene undercuff slips under my jacket sleeve and the hook-and-loop closure snugs it down, so snow can't get in at the wrist. When I pull a mitt off on the lift, the leash keeps it hanging from my wrist instead of falling to the snow below."
