Atomic ARC Retro T shirtMeant to be casual and comfortable for everyday wear, the Atomic Graphic T Shirt M was designed in house in the Austrian Alps. The retro mountain graphic on the tee is Dachstein, an iconic Austrian massif not far from Atomics HQ. The relaxed fit of the tee lets you move freely throughout your day. Stitched from a soft blend of TENCEL Modal, which is made from beech trees, the shirt has a silky, buttery feel.
