Camelbak Mule backpack with hydration bladder Caveats: - one buckle of the chest strap is missing. I never needed it, but if you do, you can request a free replacement from Camelbak under their lifetime warranty. - there is a small wear hole in the left side. See picture. - the hydration bladder does *not* come with a drinking hose. Replacement is easily sourced, however, for example see this one with additional benefit of insulation: Current version of the Mule backpack retail for $86+tax: $15 obo
