The Under Armour Men's Threadborne Speedpocket 5in Short remains flexible and cool-wearing as you rack up the miles. Stretch-woven polyester wicks moisture to facilitate cooling and flexes to conform to every move, regardless if you're finishing up a half-marathon or performing numerous reps at the gym. It sits mid-thigh with its 5-inch inseam, meaning it won't get in the way of running movements or high-octane workouts in the gym. Wide, encased elastic along the waistband won't create irritation issues, even when you're sweating profusely. Reflective hits maximize your visibility to passing traffic in low-light conditions, such as dawn and late-evening hours.
