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.

The lightweight, sweat-wicking fabric of this tee is indeed very good for workouts. However, the sizing seems to run quite small for a true athletic fit. My usual size L felt tight, almost a size down. I’d recommend sizing up if you want more room, as the current fit is a bit too restrictive for me across the shoulders.
Excellent fabric and very comfortable; perfect for all my training needs.
This Interval tee is definitely well-made and durable. It’s held up through many washes and intense workouts without showing wear. The Stone color is nice, but the fit is quite snug; it’s effective for training but not as relaxed as some other shirts. I prefer a slightly looser feel for recovery days.
Got this for my husband; he says it’s his most comfortable workout shirt.
The 'streamlined athletic fit' was far too tight around the chest and arms for my usual size. It felt more like a compression shirt than a comfortable training tee. Definitely had to return it.
