Thanks to its soft molded three-dimensional design, the 3D Hydro tank functions like a reservoir and dries like a bottle. Add the SpeedClip attachment system, integrated hanger, and drylock bite valve, and you have a unique solution.

• 3D QuickDry: The three-dimensional design with soft molding prevents contact between the upper and lower layers when open, dramatically speeding up drying time and discouraging bacterial growth.
• QuickDry Hanger: A convenient option for storage or drying above or outside the trail, built into the tank itself.
• SpeedClip Attachment System: Gregory packs equipped with 3D Hydro feature a Lock-And-Go one-handed connection between the reservoir hanger and the SpeedClip system mounted inside the hydration sleeve of the packs.
• Anatomical Fit: The three-dimensional form and full-length baffle properly distribute the weight of the tank, placing the water in a flat position on your back for optimal stability and comfort.
• Spinal Grip: A comfortable, soft-molded grip makes filling easy, and the base plate provides support along the entire length for hassle-free insertion and removal from the pack.
• Quick Disconnect: Quick-disconnect coupling for flexible tubing makes refilling easy without the need to unscrew the tubing from the shoulder strap.
• Soft Bite Valve: The lever-activated on/off bite valve allows for secure storage without leaks.
• EasyGrip Filling Port: Rubber filling port opening with integrated hose locator for built-in quick disconnect and attachment.
