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

The Interval Tank runs a little big, so I’d recommend sizing down if you prefer a more fitted look. That said, it’s extremely comfortable during heavy workouts. The fabric feels light and breathable, doesn’t restrict movement, and handles sweat really well. I’ve worn it through intense training sessions and it stays comfortable throughout. Great tank for CrossFit, HIIT, and strength training.

Great quality
These shirts are comfortable, breathable, and fit great. I just wish they weren’t so expensive. 🙄 Worth the price. I love the quality.
