Lightweight and comfortable, the Belkin F8M558BTC00 Slim-Fit Armband protects your Samsung Galaxy S4 while you're exercising. The slim design remains securely around your arm so you can focus on your workout, not your device. The stretchy neoprene material is breathable/hand-washable. Reflective fabric accents keep you safe/visible to others, making this armband ideal for anyone who exercises outdoors after dark. The larger loop for the strap makes it easier to adjust to the fit that's most comfortable for you; and your skin won't get pinched or irritated. The Slim-Fit Armband's cord storage makes sure you'll never get tangled up in your headphones. The cord storage is integrated into the strap, so all you have to do is gather up the extra cord length to keep wires out of your way.
