Not quite a tank. Not quite a tee. This muscle tank is a warm-weather essential for any guy. A custom fabric that is a blend of two yarns (55% Cotton and 45% TENCEL™ Modal). Modal comes from recycled beech wood, which is a natural and sustainable source of raw material. So, eco-friendly and naturally absurdly soft. Heyo! Alex, who starts every day with yoga and a pitaya bowl (you can Google it...we had to), is 6'1 and wears a Medium.
