THE ONLY TRAINING SHORT YOU'LL EVER NEED

ONE FOR ALL

Designed to be world’s most versatile training short, the Interval Short is purpose-built to take you through any workout - from runs and conditioning work to lifts and beyond.

NEXT-LEVEL LINER

The optional built-in liner on the Interval Short strikes the perfect balance of stretch and compression and helps you stay connected with an integrated phone slip pocket.

EVERY SESSION CARRY™ POCKETS

With dedicated pockets for your phone, keys, and cards, the Interval Short allows you to focus on your training without worrying about your belongings. Keep the essentials within arm’s reach and lock in.

NO-PINCH, NO-BUNCH WAISTBAND

Streamlined and ultra-comfortable, the waistband on the Interval Short was engineered to stay flat and stay in place, even through your toughest efforts.

LASER-CUT VENTILATION

Every pair of Interval Shorts features a column of laser-cut vents along the lateral seams that offload heat as your training output increases - so you stay cool and comfortable through your toughest sessions.

ODORBLOCK™ TREATMENT

Synthesized to neutralize odor-causing bacteria with the power of silver ions, our patented Odorblock™ treatment keeps the Interval Short smelling fresh between washes.
