"Men's On® 5"" Performance Shorts: The On 5"" Performance Shorts are lightweight men's running shorts built for training days when you want to move fast and stay comfortable. The 5"" inseam hits a sweet spot between coverage and freedom of movement, making these a solid choice for tempo runs, track workouts, or longer miles in warm weather. The breathable fabric construction promotes airflow to help keep you cool when your effort climbs.The shorts are made with a polyamide/elastane blend on the front and back panels, which keeps the overall feel light and flexible without adding bulk. An inner brief - constructed from polyester and elastane - provides a secure, supportive layer so you can focus on your run rather than adjusting your gear. The elastic waistband with adjustable drawcord lets you dial in the fit before you head out, and it stays put through the whole run. Storage options give you a place to stash keys or a gel when you need to carry the basics.Why Our Fit Experts Love It""I reach for these on faster workout days when I want something that doesn't get in the way.
