This comfortable and light-weight sport running belt is an ideal hands-free companion. Designed for a snug, bounce-free fit on the hips to prevent rubbing or chafing, you will hardly notice it's there. It is made of soft, water-resistant and strong neoprene. Adjustable elasticized waist strap to fit most hip sizes from 26" to 46". Unlike Velcro which can shift or become more difficult to grip over time, the strong buckle clip will ensure that the bottle belt stays where you want it. It allows for easy one-handed access to hydration and other essentials. Carry your essentials in the large, water-resistant zippered pouch. It is large enough for most modern day smart phones (3.75" x 7.25") as well as energy bars or other necessities. A separate inner pocket for keys, credit cards or ID will protect your valuables and keep them from being scratched. Listen to your music by utilizing the earphone cable access hole in the front of the pouch.
