On Zero 2-in-1 Shorts - Ultralight Outer with Quick-Drying Inner for High Performance Training

The On Zero 2-in-1 Shorts deliver high performance run training in a two-layer design — ultralight, loose outer shorts with quick-drying inner shorts featuring On DryTec™ moisture-wicking fabric. Secure 360° pocketing for phone and fuel, adjustable drawcord waistband with tucked drawcords for fuss-free training, and reflective detailing at the back. No slipping, no distractions, just pure performance.

Ultralight Outer with Perforated Back Ventilation

The loose ultralight outer shorts feature perforation at the back for added ventilation and comfort during high-intensity training. This construction creates no distractions during sustained efforts, moving freely without restricting stride. The engineered two-layer waistband delivers a locked-in, stay-put fit that moves with you throughout varied training paces.

Quick-Drying On DryTec™ Inner Shorts

Inner tights feature quick-drying, moisture-wicking On DryTec™ fabric to keep you comfortable and secure across sustained training efforts. This inner construction manages moisture effectively when intensity increases, maintaining comfortable next-to-skin feel throughout. The two-layer design eliminates the need for separate shorts and liner without bulk.

360° Pocketing System for Secure Storage

Built for high-intensity running, the precision-fit waistband features 360° pocketing for secure, bounce-free storage of phone and fuel. Dual drop-in pockets on both sides of the inner tights offer stable, low-profile carry for phones, fuel, or other essentials. Drawcords tuck neatly into a small pocket for fuss-free training without loose ends distracting from the effort.

Are the On Zero 2-in-1 Shorts Right for You?

The 2-in-1 construction solves two problems at once. The ultralight loose outer with perforated back ventilation handles airflow during hard efforts without restricting movement, whilst the DryTec™ inner manages moisture and provides the secure, close-fitting layer that keeps everything in place. 360° pocketing across the precision-fit waistband and dual drop-in pockets on the inner tights handle phone and fuel without bouncing or requiring a belt. Drawcords that tuck away neatly remove a common frustration of training shorts without sacrificing adjustability. Reflective detailing covers low-light visibility. If you want high-performance training shorts that handle ventilation, moisture management, and storage in a single piece without bulk or distraction, the Zero 2-in-1 delivers all three.
