NEXT-LEVEL VERSATILITY
Our commitment to perfection isn’t just about looks — it runs thread-deep. We scour the earth, searching for the finest premium materials, durable finishes, technical treatments, and advanced construction techniques to build products on an unbreakable foundation of functionality and longevity.
BUILT FOR ANY WORKOUT
From heavy lifts to daily runs and beyond, the Interval Short was engineered to handle it all. Its streamlined design and versatile build mean you can transition seamlessly between strength, conditioning, and endurance work. Whatever your training throws at you, the Interval keeps up without compromise.
ALL-AROUND PERFORMANCE SHELL
Crafted from a lightweight yet durable shell fabric, the Interval Short balances breathability with performance. It wicks sweat, dries fast, and stretches freely, so you stay comfortable no matter how intense the session. Rugged enough for the grind, refined enough for all-session wear.
DIALED-IN LINER
The Interval Short’s optional integrated liner provides the perfect balance of support and breathability. With a secure fit that won’t ride or bunch, it delivers comfort mile after mile and rep after rep. Sweat-wicking and quick-drying, it keeps you locked in and comfortable even when the intensity spikes.
EVERY SESSION CARRY™ POCKETS
Smart storage, built right in. The Interval Short features open hip pockets, a secure side zip pocket for your phone or cards, a key fob pocket in the waistband, and a no-bounce phone pocket on the optional liner — so you can move freely knowing your essentials will stay put.
COMFORT IN MOTION
Every detail of the Interval Short is engineered to move with you, not against you. A lay-flat waistband eliminates irritation and keeps the fit secure through every rep. Laser-cut vents and side slits increase airflow and range of motion. Flatlock seams reduce bulk and friction, while a strategically placed gusset enhances mobility and prevents ride-up.
Athlete-Led Design
The Interval Short was built side-by-side with serious athletes who put it through the toughest workouts imaginable. Every detail, from the pocket placement to the liner fit, was shaped by their feedback and refined through countless rounds of wear testing. The result is a short proven under pressure, designed to perform at the highest level of training.
