The CAMELBAK Thermobak Mil Spec Crux is a rugged, minimalist hydration pack built for performance in demanding environments. Its ergonomic design ensures comfort and agility, while a 3L/100oz Mil Spec Crux™ Reservoir with Quicklink™ System provides 25% more water per sip—keeping you hydrated with every use.

Easily fill, clean, and add ice to the reservoir thanks to the external fill port and two-zipper fill cover, which offers both top and bottom access to the compartment. The quick-release shoulder straps unclip for effortless removal and stow neatly inside a built-in pocket, streamlining your loadout for any mission or outdoor adventure.

Designed for versatility, the pack features a fully insulated reservoir compartment using 5mm closed-cell foam to maintain water temperature, and six D-ring points for secure attachment to any armor vest or pack with MOLLE compatibility. The adjustable sternum strap and hook-and-loop strap management system ensure a secure fit, while integrated attachment points for name tags and unit badges allow for customization and identification.

Built with 500D Double-rip Cordura® fabric, the Thermobak is engineered for strength and durability, standing up to harsh conditions and heavy use. Its minimalist profile and infrared-reflective design make it ideal for discreet operations. Additional features include grommet drain holes at the bottom of the main compartment and a BPA/BPS/BPF-free construction for safety and reliability.
