These glove run VERY small. I'm usually an extra large, so bought the largest available in the store, Extra Extra Large. I can get into them, but barely, and suspect they'd be uncomfortable (and cold) over an extended period.
Also, there's an interior lining that gets balled up when you take them off. When you then try to put them on again, you can't get your fingers into the proper finger hole. I suspect this problem would be worse when the gloves or your hands are wet.
