The CamelBak Crux Hydration Reservoir is a purpose-built water bladder designed for hikers and backpackers who want fast, reliable hydration on the trail. Its standout feature is the Crux delivery system, which uses gravity and an optimized angle to increase water flow by up to twenty percent compared to older CamelBak reservoirs. This means less effort spent sipping and more time enjoying the miles ahead, whether you're climbing a steep switchback or cruising a flat forest trail. Built from a taste-free, HydroGuard-infused material, the Crux reservoir resists mold and bacteria growth even after repeated fills, making it a hygienic choice for multi-day trips. The wide-mouth opening makes filling from streams, water filters, or kitchen sinks simple, while also allowing you to add ice cubes for cold water during hot summer hikes. The self-sealing quick-link jet valve lets you remove the reservoir from your pack without draining the entire bladder first, a small feature that saves time and prevents accidental spills at camp. Designed to fit seamlessly into most CamelBak packs as well as many third-party hydration-compatible backpacks, the Crux reservoir folds flat for easy storage when not in use and dries quickly thanks to its wide opening. Whether you're a thru-hiker logging twenty miles a day or a weekend camper who values convenience, this reservoir delivers dependable performance backed by CamelBak's reputation for durable, field-tested gear.
Customer reviews
I switched from a decade-old hydration bladder to the Crux and the difference in flow is immediately noticeable. Filling it is also so much easier thanks to the wide mouth opening.
Water flow is excellent and it never adds a weird taste. My only gripe is getting it folded back into my pack's sleeve neatly takes a bit of practice.
Used this on a five-day section hike and it performed flawlessly. The quick-link valve made refills at camp painless, and cleaning was simple thanks to the wide opening.
Overall very happy with this purchase. Occasionally the bite valve drips a little if I don't seat it properly, but that's a minor issue compared to the improved flow rate.
