Find Hydration from Gregory for outdoor

Discover the pinnacle of outdoor performance and comfort with GREGORY, a brand built on the fundamental belief that a pack should be worn, not just carried. Since 1977, GREGORY has been at the forefront of pack innovation, engineering award-winning designs that move with your body, providing an unparalleled fit that makes every trek, hike, and adventure more enjoyable. This deep-rooted expertise in carrying systems extends seamlessly into their world-class hydration solutions, designed to keep you performing at your best when you need it most.

At the core of GREGORY´s hydration line is the revolutionary 3D Hydro Reservoir, a system engineered to eliminate the common frustrations of staying hydrated on the trail. Forget the flat, sloshing bladders of the past. The 3D Hydro’s unique, soft-molded construction provides structure, which dramatically reduces sloshing and allows the reservoir to sit comfortably against your back. This three-dimensional design also has a significant advantage after your journey; it allows for complete airflow, drastically speeding up drying time and preventing mildew buildup.

Every detail is crafted for convenience and reliability. The integrated QuickDry hanger allows you to easily hang the reservoir upside down for simple, effective drying. A full-length baffle and soft-molded handle make filling from any stream, tap, or bottle an effortless task. The inline quick-disconnect feature lets you detach the hose to refill the reservoir without having to un-thread it from your pack’s shoulder strap, saving you precious time and effort. Paired with a high-flow bite valve and an integrated magnetic clip for easy stowage, the GREGORY hydration system ensures water is always accessible, allowing you to drink on the move without breaking your stride.

Whether you are looking for a standalone water reservoir to upgrade your current pack, a fully integrated hydration pack like the agile Citro or Juno series for fast-paced day hikes, or a high-performance vest for trail running, GREGORY offers a solution. Each product is a testament to the brand´s commitment to quality, durability, and a user-first design philosophy. Equip yourself with a GREGORY hydration system from trekkinn and experience the freedom of focusing on the trail ahead, confident that your most essential gear is performing flawlessly
