The CamelBak ThermoBak 3L with Mil-Spec Crux reservoir is a military-grade hydration pack that over the years has seen active use by military units all over the world.

Continuously upgraded over the last two decades and now with the Mil-Spec Crux 3L reservoir, the bladder delivers 25% more water per sip keeping you easily hydrated in the toughest of conditions.

The reservoir can be filled and cleaned without removing from the pack and the double zipped fold-down cover stays out of the way during refill.

The ThermoBak has quick-release shoulder straps that unclip so you can easily remove without feeding your arms through.

The straps can also be tucked away in the built-in pocket and the pack can then be attached to a tactical vest, body armour or MOLLE pack with the six included D-rings.

Made from tough 500D ripstop Cordura fabric, the exterior of the hydration pack has a Velcro name/unit strip, strong carry handle and a sternum strap to secure in place when on the move.

Fantastic Product.

The Thermobak 3L Crux is a quality hydration system. It keeps the water cool for several hours and it's easy to clean with the quick link system. I love it and use it daily.
