On Running Lightweight Shorts (Men's) - Navy
Ultralight, versatile shorts with a perforated back.

Technology
The Lightweight Shorts are engineered solely to help you perform better. A rear pocket and key loop secure your essentials, even when running at top speed. And, with zero zips or hard points, the shorts make light work of floor work too.

Materials
Soft but strong, the technical four-way stretch polyamide/elastane blends used in the front and inner briefs are fast-drying and offer total freedom of movement. Perforated polyester to the rear keeps you cool and the elasticated waistband hugs gently for a stay-put fit.

Design
While you're working up a sweat, the Lightweight Shorts are working on getting rid of it. Fast-drying, super-light and stretchy, their streamlined design has everything you want, and nothing you don't. Distraction-free. Because nothing should stop you chasing goals.
