Camelbak Thermobak CRUX 3.0L (Short) Hydration Pack.


The new MILSPEC Camelbak Thermobak Short is the latest incarnation of the battle-tested original. Continuously upgraded and improved continuously over the last two decades based on feedback from combat troops and military end-users. Issued to military units across the world, hundreds of thousands of troops will tell you that this is battle-winning gear.

So much more than just hydration pack. This low profile hydration carrier pack is supplied with the new MILSPEC Crux 3L Short reservoir and features integrated closed cell foam insulation. The shorter design optimizes space on the operators back and does not interfere with a duty belt or load-bearing belt system.

This is the perfect pack for shorter missions and patrols. Thermobak can be worn as a back pack or, with the harness stowed, it can be attached directly to a MOLLE panel with Grimlocs or carabiners (available in our store).
Supplied with a 3.0L / 100fl oz. MILSPEC CRUX (short) Reservoir with Quick Link™ System, the new generation MILSPEC Thermobak is ready to go!

The MILSPEC Crux Reservoir redefines the ultimate delivery system for an operator’s water supply and provides maximum adaptability for changing missions or combat environments. Larger bore tubes and fittings deliver 25% more water per sip.

Designed with end-user requirements in mind, the robust construction features MILSPEC ITW™ NIR plastic hardware, YKK® Heavy-duty zippers, 500D Double-Rip Cordura™ outer shell fabric, heavy-duty double stitching & Bar-Tacks at all stress points.
