The ON performance shorts keep the same lightweight, fast‑drying feel as ON’s core running shorts — but with a Lumos reflective finish designed for low‑light training. They look clean and minimal during the day; then under headlights or streetlamps, the fabric catches and throws light, giving you that visibility boost without changing the look of the shorts. A small zipped pocket handles keys or a card — just enough storage for everyday miles. 86% Polyamide 6, 14% Elastane Reflective Fabric Elasticated Drawcord Waistband Breathable Back Panel Supportive Inner Brief Hidden Zip Pocket Printed Branding Style Code: 1MG30900553
