Need to carry your hydration in stealth mode? The Bootlegger keeps 1.5 liters of water (or maybe something more fortifying) tucked away under your jacket with the ultimate low-profile design. It's a cold-weather version of a hydration vest, with extra-light, breathable materials and two sternum straps for a secure, bounce-free fit, plus an insulated drink tube to keep your water from freezing in cold temperatures. Plus, the new Crux reservoir delivers 20 Percent more water with every sip, and features an ergonomic design that's easy to grip even with gloves on. | CamelBak Bootlegger Hydration Pack
