Compatibility
The ThermoBak Mil Spec Crux works as a standalone hydration pack or attaches to the back of an IOTV or MTV plate carrier using the Direct Armor Attachment System. Its low-profile, shorter reservoir shape is designed to sit above the belt line so it does not interfere with a duty belt or fighting load. The Mil Spec Crux reservoir is compatible with standard CamelBak bite valves and tube accessories. This is the standard 3L model; if you need the shorter profile that fits tighter torsos, choose the ThermoBak S 3L instead.
Intended Users
Military service members rely on the ThermoBak Mil Spec Crux for patrols and field operations where hands-free hydration matters. Law enforcement officers, corrections officers, and tactical teams use it during long shifts and training. Preppers, survivalists, and outdoor recreation users also carry it for hikes, range days, and bug-out kits where a rugged water carrier is a must.
What's Included
- One CamelBak ThermoBak Mil Spec Crux hydration pack (in your chosen color)
- One 3L / 100oz Mil Spec Crux reservoir with bite valve and drink tube
A hydration reservoir cleaning kit and replacement bite valves are sold separately.
