Smartwool Men's Microweight Crew Top

The Microweight’s lightness makes it perfect for any warm-weather aerobic activity, either alone or as an undergarment. Couple this lightness with the most efficient moisture management material on the market and you get a layer that keeps you cool and dry even when your heart rate is revving up. Sure, you might still sweat the excuse you gave your boss to skip out on work for your workout...but the sweat stops there. And, because our fiber stays drier and inhospitable to odor-causing bacteria, your stench won’t give you away to your office mates.
