CamelBak's streamlined Charm carries 50 ounces of water, the equivalent of two large water bottles. The over-the-shoulder tube provides easy access to liquid refreshment and the breathable mesh harness keeps you feeling great. The Charm is compact and has a low profile so it's stable and out of the way. Plus, it has an external zip pocket for keys and other essentials.
For fast getaways and easy refills, this pack sports CamelBak's External Fill feature. It's a wide, screw-on top that lets you fill the bladder without having to remove it from the pack.
Liquid capacity: 50 ounces. Pack weight: 5.6 ounces.
