Description

CamelBak ThermoBak Tactical Hydration Pack

The CamelBak ThermoBak Tactical Hydration Pack is a no-nonsense hydration solution built for demanding environments. This low-profile pack pairs a rugged, streamlined design with the included 100oz Mil-Spec Crux reservoir, delivering more water per sip and a front fill cap for quick refills without removing the pack. Whether you're on a long-range patrol, a hunting trip, or a challenging hike, the ThermoBak keeps you hydrated and mobile.

Why the ThermoBak Tactical stands out

Unlike bulky packs, the ThermoBak sits close to your body, reducing snag hazards and maintaining a clean profile. The side-release shoulder straps allow rapid doffing when you need fast transitions, and the adjustable sternum strap keeps the fit secure and stable during movement. Hook-and-loop webbing management keeps excess strap out of the way, so nothing flops or catches.

Filling the 100oz reservoir without taking off the pack

The Mil-Spec Crux reservoir features a front fill cap with an ergonomic handle. This design lets you top off the reservoir quickly using a water source or hydration station, even while wearing the pack. No need to remove the pack—simply reach the fill cap, open it, and fill.

Built for the field

Constructed to withstand demanding conditions, the ThermoBak Tactical is a reliable choice for tactical professionals, outdoor enthusiasts, and anyone who needs hands-free hydration in tough environments.
