On Running

5in Performance 2/1 Short - Men's

What Our Gearhead® Experts Are Saying:

"I wore these through a full marathon training block and the inner tights never rode up or caused friction, which is a bigger deal than it sounds over long miles. The zipped back pocket holds my nutrition securely and the four-way stretch means I never once thought about what my shorts were doing."

The best running shorts are the ones that never cross our mind mid-run, and the On Performance 2/1 Short earns that status fast. Four-way stretch fabric moves in every direction without resistance, and the quick-drying construction keeps things feeling fresh whether we are five miles in or fifteen. The 5-inch inseam hits the sweet spot between freedom and coverage for both road and track efforts.

Layered inner tights add comfort and eliminate the need for a separate base layer underneath, and a dedicated side pocket on the tights keeps small items accessible without adding bulk to the outer shell. A zipped back pocket secures valuables or mid-run fuel, while a waistband storage pocket handles the extras. Reflective On logos extend visibility into low-light training windows, rounding out a short that is built to support the full weight of a serious training schedule.
