The CamelBak Hydration Packs story began in 1988 when a bicycle enthusiast named Michael Eidson, EMT by day, discovered a clever hands-free way to stay hydrated during a 100-mile road race. Michael filled an IV bag with water, put it in a tube sock then stuffed that into the back of his jersey with a thin hose clamped by a clothespin attached. Michael was able to drink while pedaling and thus hands-free hydration was born. Since then, CamelBak has invented the hydration category and become the world's leading maker of hydration solutions. Used the world over by not just outdoor enthusiasts, but by the most elite Military personnel. With packs specifically designed for nearly any outdoor activity one could conceive of made with the highest quality materials, CamelBak strives to keep you hydrated wherever the road, river, dune, slope or trail takes you. All CamelBak products are backed by their Got Your Bak Guarantee: "If we built it, we'll Bak it with our lifetime guarantee".
