Get ready for a sweatshirt with half the zip and double the thickness. Our Double Thick Zip Sweatshirt features two layers of thick, 13 oz. 100% pre-shrunk cotton fleece for warmth, plus gusseted armpits for freedom of movement. The 1/2 Zip front on this heavy duty sweatshirt extends past the chin for additional coverage in colder weather.
