CamelBak ThermoBak Mil Spec Crux 3L 100oz Hydration Pack

Overview of the CamelBak ThermoBak Mil Spec Crux | 1683001000P

CamelBak ThermoBak Mil Spec Crux (3L/100oz), MPN 1683001000P, is a low-profile hydration pack built for people who need water within reach and their hands free. You can wear it as a standalone pack or attach it to the back of an IOTV or MTV using CamelBak's Direct Armor Attachment System (D.A.A.S.).

Water where you need it

The updated 500D double ripstop Cordura shell shrugs off abrasion, while the new 3L (100oz) Mil Spec Crux reservoir delivers 25 percent more water per sip. Quick-release shoulder straps unclip and stow inside a built-in pocket, and an adjustable sternum strap with hook-and-loop management keeps the harness dialed in.

Built for real work

For a soldier on a fast patrol, a corrections officer on a long shift, or a prepper packing a ready kit, the ThermoBak Mil Spec Crux (1683001000P) keeps hydration simple, insulated, and close. Choose black for everyday duty or coyote or multicam for a low-visibility field look.

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
