Two layers of super thick fleece. Arborwear doesn't take this "sweat" thing lightly. Thicker...er. Two layers of thick, 12 oz. 100% pre-shrunk cotton fleece for warmth, and gusseted armpits for freedom of movement. 1/2 Zip front extends past chin for added coverage in colder weather. Vertical, recessed hand warmer pouch.
