I've been wearing these gloves for everything outside over the past couple of months. They are incredible. I get cold hands, and usually have to use hand warmers, but not with these quality leather mitts. They are much warmer than a pair of Hestra Mittens I own. They've been great for downhill skiing as well as backcountry skiing, and walking the dog. My hand is a 9", and I got the size XL, which fits a little snug now, but I'm sure will expand over the years. The build quality and craftsmanship is great, not a cut on them after regularly handling sharp ski edges. Of course they are 100% waterproof. Can't speak more highly of these mittens!
Outstanding quality and craftsmanship and very warm. Best part is as you use them they get softer and form to your hands. They seem so minimalist (not bulky) but my fingers have plenty of room and are as warm as heated gloves.
The quality of the materials is better than what I've experienced with many high end brands like Arcteryx or OutdoorResearch. They seem to fit tight, but also seem to be stretching as I wear them more. Overall very nice!
