The 5K Jacket M from Swix is a men's running jacket with a hood. It is made from lightweight 4-way stretch fabric with a water-repellent DWR finish, allowing it to move with you during your run while keeping wind and light rain out. The slim fit, elastic side panels in the hood, and elastic cuffs provide a flexible feel during exercise. The chest pocket with zipper holds small essentials, while the vented slits help regulate body temperature during intense activity. Reflective details on the front, sleeves, and back increase visibility in low light.
