Product details:

Working out never felt as good as it does with the Icebreaker Men's BodyFit 150-Ultralite Anatomica Long-Sleeve Crew. Its fine-gauge merino wool regulates your body temperature while you run, so you're comfortable whether you're sweating up a storm or feeling the nip in the morning air. Merino is naturally antimicrobial, so it stays fresh after multiple uses. And a bit of Lycra adds the stretch you need for a full range of motion in this slim-fitting shirt.
