When you don't need a full-sized bottle of liquid, grab this one! The handheld's ergonomic configuration allows your hand to relax to a natural position - eliminating hand cramping and tension. The strap is a combination of Ballistic/Ripstop nylon pocket and a soft, wicking inner layer that doesn't trap sweat. The quick-adjust strap allows for a custom fit. Comes with a custom molded 12 oz. Hydraform Bottle. BPA free.
