The TuneBand for iPhone 5S provides a comfortable way to wear your device while running, working out, working in the yard, or walking around the block. It features a protective silicone skin that allows access to all ports and buttons (including the front and rear cameras), and a soft, elastic strap that fits most arms. We also include a screen protector that covers the front of the iPhone. This tuneband was specifically designed for using the new Touch ID on iPhone 5S. NOTE: The TuneBand for iPhone 5S is designed to work with a bare iPhone 5S *only*. Some customers have reported success installing our silicone skin over their existing iPhone cases, but this use is unsupported by us. Also, if the included elastic strap is either too long or too short, then please contact us at support [at] grantwoodtechnology [dot] com to arrange a replacement strap. We also mention this in the included thank-you card.
