K228 Carhartt Heavyweight Cotton Thermal Crew Neck Top

Like all Carhartt thermal underwear, we've designed this midweight cotton crew neck top for comfort, warmth and durability. Made of premium, 9.5-ounce, 100% cotton, it features rib-knit neck and sleeve openings that keep warm air locked in.
The fabric, which is 30% heavier than most other cotton thermals, also traps body heat in for warmth.
All seams are flat-locked for added durability, comfort and strength, and its low shrinkage provides a consistent fit.
For function, ruggedness and ease of movement, this job-tested crew neck has it all.
