Nathan designed the Elite 2V Pack with the elite trail runner in mind, so it wont flop around uncomfortably on your waist. The two holsters on this ultra light lumbar pack hold your water bottles at an angle so you can reach back and grab your H2O while on the go. Two removable front zippered pockets let you stow ID, energy gel, anti-chafing cream, and other small essentials. A shock cord between the water bottles tightens to hold a jacket or gloves. Fits waists 26 to 42 inches.
