Interval Tank

The Interval Shirt is the gold standard for training shirts. It’s built to move fast, breathe easy, and handle every workout without compromise.

Constructed from lightweight, sweat-wicking fabric with high-stretch mobility, the Interval Shirt is equally at home in max-effort conditioning, tough strength days, and miles on the road. Bonded seams and a streamlined fit ensure comfort that never distracts. This is the shirt built to push the limits.
