These gloves are plenty warm for cold north face climbs. Normally this would mean that dexterity would suffer. This is not the case, as these gloves allow you to manipulate ice screws, screwgate biners and belay devices. I used these babies for ice climbing over in Chamonix and had no issues. The fit is initially very snug, I thought I had the wrong size. If you wear the gloves a few times, they break in and start to feel true to size. Took about three wearings before they finally felt like a large.
