Anonymous wrote a review of Marmot Expedition Mitt on February 11, 2008
These are the warmest handwear I've ever worn, including others from marmot like the randonee mitt and the ultimate glove. I took them skiing when it was -10 degrees outside (-27 with wind chill) and my hands were toasty, even sweating after some of the more difficult runs. I have been using them all of this ski season and they show no signs of wearing out. The only downside to these is that because they are so stuffed full of insulation, it is a bit harder to fasten helmet buckles and open up my cell phone. However, it's not too much of a problem, and holding on to ski poles is no harder than any other mitten, contrary to other reviews. Also, the inner and outer liners are attached along the top portion of the mittens. Overall, I would highly recommend these mittens. NOTE: buy them a size smaller than you normally would wear, they run a bit large.
