Guys take a size down (my husband usually wears a size M), on purpose and due to several previous purchases of ColdPruf products I've taken a size S as they need to stretch and fit a bit and they should keep him warm too. And they do their thing, his ass isn't cold anymore! My husband is very grateful. Highly recommended! Soft, warm, beautiful, comfortable, great quality, they don't itch, don't tug tiny hairs (if you know what I mean) and you can wash them as many times as you like :))))! Thanks, ColdProof! Excellent work!
