FREEDOM TO MOVE STAY DRY ON THE FLY An ideal light layer for an unexpected run or rain shower, the Nike Flex Men's Short-Sleeve Running Jacket is versatile and packable. Its woven Nike Flex fabric stretches in four different directions for unrestricted movement and has a water-repellent finish to keep you dry. The elongated silhouette is modern, sleek and simple. Versatility in the Rain With a loose fit and short sleeves, the pullover is great over your tank or long-sleeve crew top—the perfect amount of coverage so you don't overheat. If a surprise rain shower rolls in, the DWR (durable, water-repellent) finish helps block moisture. Smart Details The half-zipped design allows for quick ventilation. To keep the unzipped neckline from flapping as you run, a fabric gusset has been added. The gusset is perforated to help air flow and body heat escape. Packable When the rain clears, the jacket packs into its drawstring pouch, found attached inside the zipped kangaroo pocket. Packing it up reduces bulk and makes it easier to throw into a tote bag or backpack.
