Great mitt. Excellent for belay or biking to about -20 C with a thin liner for me. Nice to be able to easily shove them down into a pocket. Relatively dexterous for a mitt, medium fit just right for use alone or with a liner under, similar to other OR gloves for me. Worth noting - either from a couple months use biking, skiing, and climbing (all involving a lot of gripping stuff) or how they came, there isn't a ton of insulation on the palms. This is generally good for having decent grip, but one thing that reduces how warm they are. Also, they aren't all that water resistant - throw on an overmitt if you're planning to get in the snow.
