The lightweight Elite 1 hydration waist pack comes with a 22 oz. hydration bottle, which fits into the angled & insulated holster, allowing quick access. This is helped by performance features such as the XTS cradle. The XTS Cradle securely hugs the hydration bottle but allows for smooth, easy bottle removal & replacement. Another feature is the zipped mesh pocket for small essentials. Moisture Wicking Lumbar Back material is used which pulls moisture away from your body, increasing comfort & reducing potential chafing. The limited stretch elasticized waist belt helps to access the bottle, as well as to aid in better belt placement & unrestricted movement. There is also a sleeve for ID or medical information for extra safety. Fits 26"" to 42"" waists.
