Men's Thermal Long Johns - Double Layer Base Layer Leggings - With Pouch

Warm Legs All Winter, With Nothing Extra Underneath

Tired of wearing boxers under baggy long underwear that bunches and sags all day? These men's thermal long johns combine both in one piece, so you get a warm, close-fitting base layer with built-in support and no extra layer to fuss with.

Why these long johns stand out:

• Double-layer knit — a soft inner layer holds your body heat close, so cold mornings outdoors feel a lot milder.
• Two-in-one design — works as underwear and base layer at once, so you pull on one garment instead of two.
• Built-in support pouch — a shaped front pouch gives room and support, so nothing pinches when you walk, sit or bend.
• Stretch fabric — the polyester and elastane blend moves with you, whether you are shoveling, hiking or driving to work.
• Elastic waistband — stays put without digging in, and the slim fit slides smoothly under jeans or work pants.
