My hands are always cold. There is not a glove in the world that will keep my hands warm enough, so I turn to mittens. I wore these mittens last season for about 100 days in Montana, from cold to warmish. I am a snowboard instructor, so my gloves get a lot of use taking bindings on and off of myself and students. These mittens held up very well, with little wear on the leather and my hands were warm on all but the coldest Montana days (-10 degrees and colder). On really cold days, I put a hand warmer inside and was good to go. There is no internal glove in these mittens, so the hand warmer works well. I'm buying another pair for this season just in case my others wear out!
