Croft and Barrow Men's Thermal Pants. Also called long winter underwear, the Thermal Pant is a snug-fitting base layer worn underpants to keep you warm in cold weather. The top portion fits snug and supportive, like a boxer brief, and features a functional fly for easy access. The soft, waffle-textured fabric is thick enough to keep you warm, but thin enough to fit under a variety of pants, even jeans. 2 Pack
