Here's what other sites are saying:
Light and fast is what the Men's Nike 4 inch 2-In-1 Shorts are. These great running shorts have built-in compression shorts for ultimate support, and with the Dri-FIT sweat-wicking, breathable material, you cant be anything but light and fast. Reflective stripes on the sides help with low light visibility and with an interior key pocket and zip pocket at back waist, you can keep small valuables close while you pick up the pace and run like the wind.
