Key Features

Scrunch Detail

The signature scrunch at the back is knitted directly into the fabric — not added on top. It's a construction-led design feature that gives the shorts their distinctive look without compromising fit or comfort during movement.

Seamless Construction

Seamless knit technology means there are smoother feel during wear seams or irritating stitching to contend with mid-session. The fabric wraps the body cleanly, reducing friction points across the full range of motion.

High-Rise Waistband

A wide, elasticated high-rise waistband sits securely at the waist without folding or rolling. It stays in position through lunges, jumps, and everything in between, so you're not adjusting your kit between sets.

Soft-Touch Fabric

The seamless knit used across the collection has a soft-touch feel that's comfortable straight from the first wear. The stretch is generous in every direction, so the shorts move with you rather than against you.
