What Our Gearhead(R) Experts Are Saying:"I wore the On Running Performance Short Tights through a full summer of track workouts and warm weather road runs and they never once needed adjusting mid-stride. The high waist stays exactly where you put it, the key loop in the side pocket is a small detail that solves a genuinely annoying problem, and the five inch inseam hits a length that works for hard efforts without ever feeling restrictive."Warm weather running asks a lot of what you wear. The On Running Performance Short Tights answer with a close-fitting, high-waisted construction that compresses, breathes, and stays completely out of your way from the first stride to the last. At a five inch inseam, the length is dialed for unrestricted movement without any of the bunching or riding up that shorter cuts can bring. On built these tights from the same 75% recycled polyester and 25% elastane blend that defines the Performance range, fast-drying and moisture-wicking so that heat and sweat move away from the skin rather than settling in. The high waist holds its position under effort without needing attention, and the pocket setup covers every run-day essential. Three mesh waistband pockets sit at the rear for easy access, while the side mesh pocket includes a built-in key loop so the one thing you cannot afford to lose stays exactly where you put it.
