I usually wear a small, but after reading other reviews I ordered a medium and am happy that I did. The gloves are comfy, but don't offer as much dexterity as I was hoping. I have to take them off most of the time to tie my shoes, fish out keys to open the door, etc. They are waterproof and protective in the snow for cross country skiing, but only work if your hands are already warmed up (as I suppose is the case with most gloves). I'm happy with the product, but probably could have found something comparable at a lower price.
