On Running Ultra Shorts Mens | Lightweight Trail Shorts

Made for Trail Speed
Take on every terrain with confidence. The On Ultra Shorts are engineered with ultralight, stretchy technical fabrics that reduce weight and elevate comfort on the trail.

Superior Storage, Zero Bounce
Designed to be practical yet lightweight, these shorts pack six efficient pockets: four easy-access mesh pockets in the front waistband, a side seam pocket, and a secure zip back pocket—perfect for gels, phone, keys, or a compact windbreaker.

Comfort Inner Brief & Snug Fit
A super-soft integrated brief delivers a chafe-free experience no matter how many miles you're racking up. The adjustable waistband ensures the shorts stay securely in place—even when fully loaded.

Built for Performance
The bonded hem and streamlined silhouette reduce distractions and minimize friction on the trail. Swiss-engineering details like the hologram logo add a premium touch.
