CamelBak Crux 3L Hydration Reservoir
The CamelBak Crux 3L reservoir holds a full 100 ounces — enough for a long summer day hike — and delivers 20% more water per sip than older CamelBak designs thanks to the high-flow bite valve. The Quick Link system disconnects the hose from the reservoir without emptying it, so you can refill and filter at a stream without threading the tube back through your pack. The leak-resistant cap threads on with an ergonomic handle for fast fill-ups, and the on/off lever at the valve seals the tube shut when you're not drinking.

Somewhere around the third hour of a hot hike the old bladder starts hissing air - you tilt it, squeeze it, and get a trickle when you need three gulps, and the bite valve leaks down your shirt every time you set the pack down. The Crux 3L holds a full 100 oz, its high-flow valve delivers 20% more per sip, and the on/off lever seals the tube so drips stop when you are not drinking.
🏆 How It Compares
Against the 2L Crux, the 3L adds 30 oz for roughly the same money - the right call for all-day hikes and family trips where refills are scarce. The catch: it holds about 6.6 lb of water when full and needs a pack with a 3L sleeve (the bladder alone fits no pack), plus periodic deep cleaning to keep mold out of the hose.
