Ten Thousand's best-selling training short. Overbuilt for all the ways you train, from strength days to interval sessions, and backed for a full year.
Get The Interval Short
The waistband folds over and digs in at the bottom of a squat. The phone slaps your leg on every interval. The liner dies by month three. You know the drawer those shorts end up in. This one was engineered to stay out of it.
Every piece of the build maps to a specific way ordinary shorts fail.
A responsive shell that moves in every direction a session asks for. It squats with you instead of fighting you.
A no-pinch waistband that stays put under a bar and through burpees. No fold-over, no dig, no readjusting.
Vents cut into the fabric itself to keep you cool through the toughest sessions. No sewn-in mesh to trap heat or wear out.
A pocket system that secures your phone, keys, and card without bounce. Essentials stay put while you move.
Your call. The short comes both ways, and the 7-inch is also made in 5-inch and 9-inch cuts.
"If an item does not perform as intended within 1 year of purchase, we will replace the item."
Terms quoted from the live Ten Thousand quality-guarantee page, 2026-07-16. It is a 1-year guarantee, plain and simple.
The four-way stretch shell and no-pinch waistband hold their ground at the bottom of a squat and under a loaded bar. Nothing rolls, nothing digs.
Laser-cut vents dump heat while Every Session Carry™ pockets keep your phone and keys from bouncing through sprints and circuits.
Pick your liner, wash it, and put it back in the bag. One short covers the whole week, which is the entire point.

Ten Thousand's stated terms: if an item does not perform as intended within 1 year of purchase, they will replace it. You need to have bought it at tenthousand.cc and have proof of purchase, your order number and purchase email. Claims are reviewed case by case, one claim per item. Normal wear and tear, final sale items, misuse, improper care, and alterations are not covered. If the item was discontinued, they issue store credit instead.
No. The 7-inch is the flagship cut, and the Interval Short is also made in 5-inch and 9-inch versions on the Ten Thousand site.
Black is the staple, alongside a set of muted colorways such as Stone, Navy, Iron, and others. Exact availability varies by size on the live product page.
The site lists free returns and exchanges, and free shipping on orders of $150 or more. A single short is under that bar, so standard shipping rates would apply unless you build a bigger order.
