Like down jackets for your hands - C.A.M.P. Summitt'n Mountaineering Mitt - Unisex

I tested these in Autumn weather in Alaska. That means its already subzero. These are very lightweight, true to size, very flexible and compress-able. They shed water well although I sprayed them with Camp Dry prior. I like the leather palm. Very well made! Not musher-worthy but for everything else, excellent.
