Linda Freeman wrote a review of Burton Gore-Tex Mitten - Women's on December 14, 2012
Familiarity: I've used it once or twice and have initial impressions
I went outside in a not so cold day to just see how they felt. Within seconds or a minute I began to feel the mitten almost heat up, got nice and warm. The Insulator mitten didn't do that. I haven't skied in them yet, but I think the other rec and my first impression would call this one a good one to try. The liner has some rubber looking patchwork on the palm and it comes out of the mitten, essential if you have to use your hands for something. I really like these, just haven't trail tested them yet.
