Add strength training to your cardio workout with the CAP Adjustable Weighted Vest. The vest is made with breathable mesh with adjustable clips to match your body type. Once on, the vest helps you gain strength and burn additional calories regardless of your activity, from aerobics to sports. The vest is weight adjustable, with each steel-shot packet weighing approximately 0.75 lb. Just start with just a few weight packets and then add more as you get stronger. Other features include reflective safety strips to keep you out of harm's way after dark and an integrated pocket for an MP3 player or cell phone. Built with neoprene padding for comfort, the vest's one-size-fits-all design fits both men and women.
