Heat Holders Mens Cotton Thermal Underwear Bottoms Long Johns

Heat Holders Men’s Cotton Thermal Underwear Bottoms are long johns made for cold-weather layering. Thermal construction holds warm air close to the skin, creating a slim base layer that sits smoothly under clothing. The set has a TOG rating of 0.45 for an added layer of warmth when one layer is not enough.

Technical construction and a supportive fit follow the body’s natural contours for a close, low-bulk feel under everyday outfits. The base layer uses a soft modal material for comfort and warmth, while the elasticated waistband provides an easy, secure fit. Available in black, grey and white.
