When you want the unrivaled, lush, warm feel of cotton, pull on the Men's Carhartt Heavyweight Cotton Thermal Underwear Top. Made with 9.5 ounce 100% ringspun cotton thermal, this top is 30% heavier than most other cotton thermals, trapping more body heat and providing that thick, dense enveloping feel of comfort and contentment. We all know cotton is a poor choice for high intensity, sweat-inducing activities, but for low intensity output, and casual wear, it definitely has a feel we love. Flat-locked seams reduce the potential for chafing, and a low shrinkage knit means you won't have to give it to your girlfriend after one washing. It also has a rib knit collar and cuffs for added heat retention and a lasting fit. From casual pub wear, to a day in the shop, enjoy the warmth, durability and comfort of the Heavyweight Cotton Thermal Underwear Top for men from Carhartt.
