The Moshi armband holder is designed to keep your iPhone within easy reach while running. No more searching or fumbling to get your smartphone out of your sleeve or pocket. A stable, mechanical MetaMount lock securely holds your iPhone in place and features a quick-release button, allowing you to remove it instantly to reply to a text or answer a call. The strap is made from soft, breathable, and elastic material, and there is a non-slip silicone pad on the back of the holder to keep the device securely in place.
