Twenty years of combat-tested design and innovation has gone into the Camelbak Military 3L Backpack which has made it popular with thousands of service personnel across the globe. Still featuring a tough 500 Denier Cordura rip-stop exterior, the Thermobak is ready for anything. Quick-release shoulder straps allow for fast removal and external fill options, plus a fold-down fill-port cover makes refilling the completely insulated 3 litre reservoir easy without having to remove it from the pack. For greater security and a much more comfortable fit D-ring attachments allows the Camelbak Military bag 3L Backpack to be added to an armour vest or once the shoulder straps have been unclipped can even be attached to another backpack that uses the MOLLE system.
