On Zero Shorts - Lightweight Performance with Built-In Storage

The On Zero Shorts combine lightweight construction with practical storage for training and race day. Engineered with stretch-woven fabric on the outer and a quick-drying soft-feel inner brief, these shorts deliver distraction-free performance whilst providing the ventilation and pocket capacity needed for longer efforts.

Ultra-Lightweight Race-Ready Construction

The outer uses stretch-woven fabric engineered for race day performance, keeping weight minimal whilst allowing natural movement. A soft-feel, quick-drying inner brief provides comfort without bulk. An adjustable waistband delivers a comfortable, customisable fit that stays secure across varied paces.

Perforated Fabric for High Ventilation

Perforated outer fabric improves ventilation, helping you feel fresh as you pick up the pace. This strategic perforation provides airflow where heat builds up most, particularly valuable during faster efforts or warmer conditions.
