Description
SINCE 1977
Our founder, Wayne Gregory was born with a simple passion to design backpacks he could trust on the most ambitious of life adventures. He did this by pioneering new suspension systems with a relentless attention to anatomical fit that works with your body instead of against it.
MAKERS AT HEART
Our packs are designed with hand-crafted prototypes made by skilled artisans at our headquarters in Salt Lake City, Utah.

The Gregory 3D Hydro 3L Reservoir is built to be easy to clean and easy to fill, with all the adaptability we need for our biggest adventures. The Hydro is constructed with a soft-molded 3D shape that’s self-supporting and prevents the bottom and top layers from folding in on themselves, which promotes a faster dry time and limits bacterial growth. A full-length baffle along the interior of the bladder discourages the reservoir from sloshing around as we hike or bike. Meanwhile, the crescent-shaped handgrip makes for an easy, spill-free filling experience, and the QuickDry Hanger provides effortless storage and drying once we’re done for the day.
- 3D QuickDry: Soft-molded 3D design prevents contact between top and bottom layers when hanging open, dramatically speeding drying time and discouraging bacteria growth.
- QuickDry Hanger: A convenient option for storage or hang drying on or off the trail, integrated into the reservoir itself.
- SpeedClip Mounting System: 3D Hydro enabled Gregory packs feature a one-handed lock-and-go linkage between the reservoir hanger and the SpeedClip system mounted inside the packs hydration sleeve.
- Anatomical Fit: 3D form and full-length baffle properly distribute the weight of the reservoir by positioning the water flat against your back for optimal stability and comfort, without adding weight and cylindrical bulk.
- Spine Co-Molded Handle: A comfortable, soft-molded handle makes filling easy, and the co-molded baseplate provides full-length support for hassle-free insertion and removal from the pack.
