The new smartphone is so much more than your average cell phone, and that's exactly why you put yours to work as a mobile entertainment and inspiration powerhouse when you're active and on the go. This protective workout armband keeps your smartphone snug against your arm for optimum convenience while running, biking, skating, aerobics, or any other type of physical activity that has you bouncing around. With its reflective design, it's even visible at night, so it's the perfect late evening stroll companion. The Velcro strap closure cinches tight around the bicep of either arm and the case shields the phone from impact and moisture. Get out and push yourself--and keep your iPhone 4/4S, iPhone 5, or iPod Touch in just the right spot.
