Stay warm and dry all day long with the Carhartt Force Midweight Men’s Thermal Base Layer Pant. Engineered with Rugged Flex technology and smooth flatlock seams, this thermal underwear provides unrestricted movement and chafe-free comfort to power you through any cold weather activity.

Unbeatable Warmth That Moves With You

The midweight interlock knit traps body heat while wicking away moisture. The smooth, flatlock seams prevent skin irritation for all-day comfort. Strategically placed seams maximize your range of motion. So whether you’re working outdoors, hiking through the wilderness, or ice fishing in the freezing cold, this Carhartt base layer keeps you warm without restricting your movement.

Fights Odor and Dries Quickly

The Carhartt Force thermal pant is treated with FastDry technology that wicks away sweat while you work and move. This prevents chill and fights the growth of odor-causing bacteria. Even after a long day of heavy activity, this base layer keeps you feeling fresh. The midweight interlock knit also ensures the material dries quickly, so you stay comfortable throughout changing conditions.

Tagless Label and Lay-Flat Waistband

Like all Carhartt base layers, the Force midweight pant has a tagless label to prevent skin irritation. The label is printed directly onto the fabric. The concealed waistband lies smoothly against your skin, with no bulky elastic or thick seams. This lay-flat waist keeps you comfortable under outer layers.

Built Tough for the Outdoors

As a trusted leader in workwear and outdoor gear, Carhartt builds the Force base layer pant to handle even the harshest environments. The durable interlock knit stands up to snags and abrasion while you’re trekking through brush. Raglan sleeves ensure full range of motion for climbing and chopping wood. This pant is machine washable, so you can keep it fresh season after season.

Versatile Cold Weather Base Layer

The Carhartt Force thermal underwear works as part of a versatile layering system. Wear it as a base layer under jeans or rugged Carhartt pants and jacket when working outside in cold temperatures. It also makes a great first layer for hunting, hiking, camping, and other outdoor activities. For extreme cold, layer it under snow pants and jacket for maximum warmth.
