Nathan Hydration 2014 Shadow Pak Runner's Pak 4819N

Runners and walkers should always exercise safely, which means carrying an I.D. and a cell phone. To encourage more athletes to carry these and other important essentials, Nathan has developed the Shadow Pak, a waist pak that, just like its namesake, is always there but never felt. Its mesh, gusseted pocket expands to hold any sized cell phone, leaving plenty of room for lip balm, keys, money, and other essentials. And its incorporated. I.D. card means, in case of an emergency, help will have instant access to your identification, contact info, and relevant medical history.
