Weightless Muscle Tank

The Weightless Muscle Tank is made from sustainable beechwood fibers, ingeniously blended to give you the four-way stretch, moisture wicking, and odor resistance you need. It's a shockingly lightweight sleeveless tank, with dropped armholes for a full range of motion and no top shoulder seams for a chafe-free workout.

After decades in the apparel industry becoming frustrated with shoddy fabrics and wasteful production, the family-led team at tasc decided to create a better way. The brand's activewear bread and butter is bamboo viscose, which boasts the breathability, moisture-wicking, and anti-odor properties of traditional activewear — with none of the plastic or petrochemicals.
