A virtually brand-new CamelBak H.A.W.G. Mil-Spec hydration pack. 

This bag has been used exactly once. It is in immaculate condition with no tears, stains, or signs of wear. It’s the closest you can get to a retail-fresh bag without paying the full $235+ price tag. I'm also including 2 molle straps and a olive drab camelbak rain cover.

Has 500D Double-rip Cordura® Fabric, this pack offers the ultimate combination of strength and lightweight resilience. Includes the 3L (100 oz) Mil-Spec Crux Reservoir, the hydration compartment is dedicated and insulated to keep your water cool for hours. Has 23L of total capacity and the front features Extended Mountain MOLLE for secure attachment of extra pouches and gear. Also features an air Director back panel for breathability and padded independent suspension harness and a removable waist belt and side-release shoulder straps for rapid removal.
