Hyperice Vyper
It might not look like much, but if you're an athlete (or just an active person), the Hyperice Vyper could make a huge difference in your workouts and recovery. Powered by a rechargeable lithium ion battery, the Vyper delivers three speeds of vibration through a high-performance, air-injected polypropylene shell. The combination of the vibration and the pressure from the shell work to improve your performance by loosening muscles, increasing flexibility and range of motion, and boosting your overall well-being.
