Men's Thermal Underwear Set - Long Johns Top and Pants - Base Layer

This men's thermal underwear set is a two-piece base layer: a long-sleeve crew-neck top and full-length pants, made to go on first and sit flat under the clothes you already wear. Top and pants come together in the same close fit and color, so you are covered from wrist to ankle in one purchase.

Both pieces are knit from a medium-stretch fabric that is 95% polyester, cut close to the body so they lie flat under jeans, work pants and a jacket instead of gathering at the knees and elbows. The pants sit on a wide black elastic waistband with a contoured front, and the top carries a tonal line print across the chest.

Cotton long johns are the usual first try and the usual complaint, because cotton holds on to sweat and turns cold once you stop moving. This set is a polyester knit instead, and the stretch lets it move with you when you bend, kneel and reach.

Whether you are working outside through a winter shift, sitting in a deer stand at first light or walking the dog on a frozen morning, this set gives you warmth underneath without bulk on top.

Key Features:

• A long-sleeve crew-neck top and full-length pants come as one set, matched in fit and color.
• The close stretch-knit fit sits flat under jeans, work pants and jackets without adding bulk at the knees or elbows.
• Sleeves run to the wrist and legs run to the ankle, covering the gaps where cold gets in at glove cuffs and boot tops.
• Medium-stretch knit moves with you when you bend, kneel and reach through a work shift or a day outdoors.
• A wide elastic waistband holds the pants in place under outer layers without a belt.
• The fabric is a 95% polyester knit rather than cotton, the fiber most likely to stay damp against your skin.
• Wear it as a winter base layer for outdoor work, hunting, ice fishing and cold commutes, or as warm sleepwear on cold nights.

This is the layer you pull on in the dark before a cold day and stop thinking about once your jeans go on over it.

Pair it with our fleece-lined softshell hiking pants for cold days on the trail.
