The Camelbak Motherlode hydration pack is designed tough for extreme outdoor uses. The pack has an integrated Military Spec 3L hydration reservoir and 37 litre cargo capacity with exterior pockets and front MOLLE panel for additional storage. This rugged backpack offers a combination of features to increase your comfort while carrying your load over distances including a low centre of gravity thanks to the design of the reservoir and its compartment, 50 mm webbing waistbelt, adjustable sternum strap and quick release shoulder harness. The backpack itself is made to last from durable 500D Double-rip Cordura Fabric. The Motherlode backpack comes with a top of the line Camelbak 3L Mil Spec hydration reservoir. Unlike civilian reservoirs, this one is built according to military specifications from tougher materials and is configured to have a lower centre of gravity with a low/wide design. This puts the weight of the water lower in the pack and distributes weight off the shoulders. Additionally the hydration reservoir has a fast output through the ql hydrolock Bite valve adapter. Refilling and repacking the reservoir is easier due to the quick link exit port, large ¼ turn opening and access to the reservoir compartment through its own exterior zipper.
