Made of 50% cotton/50% polyester fabric, our Carhartt K121 midweight hooded pullover sweatshirt works well when the weather turns cool. Comfort is enhanced with its attached hood with draw-cord closure. Front hand-warmer pockets are standard, as are its rib-knit cuffs and waist band that keep out the cold and seal in the warmth. Charcoal Heather fiber content is 55% cotton / 45% polyester. Heather gray fiber content is 70% cotton / 30% polyester.
