Get the lightest running experience in the On Lightweight Shorts.

On created the Lightweight Shorts to eliminate distractions. Designers cut the front panel and inner brief from a polyamide-elastane blend fabric for its mobility and quick-drying properties. The rear panel is a perforated polyester for breezy comfort and minimal weight.

A soft waistband with an elastic drawcord lies flat against your body, and a pocket with a key loop hides away in the back of the waistband. With no zippers or hardware, the Lightweight Short makes easy work of foam rolling, too.

Weighing less than 4 oz, the On Lightweight Short doesn’t draw any attention to itself so you can focus all your effort on your workout
