Flex Stride 5in BF Short - Men's

Even when those long training days have your muscles feeling tight, the Nike Flex Stride 5in BF Shorts will still flex with ease. They're made with a lightweight, flexible, and moisture-wicking fabric that'll work to keep you comfortable in just about every way it can. Your stride will be free and easy as your shorts stretch, and your skin will feel cool and dry as the Dri-FIT technology wicks away sweat. In addition to the light and stretchy inner lining that supports and comforts throughout your whole run, there's also a perforated area at the back of the shorts that lets in breathable airflow to regulate your temperature on hot days. A zippered phone pocket in the back keeps your smartphone securely stashed while you run, and even has a vapor barrier to keep your phone protected from damage as you sweat, so you can always be tracking your times and distances.
