The BPA-free Osprey 2L HydraForm reservoir conforms to your back's shape even when full, resulting in a precise, stable and comfortable fit.

  • Reservoir sandwiches an anatomically shaped plastic sheet between a layer of nylon fabric and the reservoir back
  • Rigid spine/handle stabilizes the water load and makes it easy to slide the reservoir into the pack; large mouth makes filling and cleaning it a snap
  • BPA- and PVC-free reservoir does not retain tastes or odors and features AquaGuard™ antimicrobial formula which inhibits bacterial growth
  • Osprey 2L HydraForm reservoir has a 180° pivoting on/off valve that rotates for quick flow control; magnetic sternum-strap buckle secures the bite valve when not in use

Osprey 2L HydraForm Reservoir - 70 fl. rated5.0out of5by2.
Rated5out of5byfromPerfect reservoir, great featuresWorks very well, no leaking even after I basically sat on it. The magnet on the bite valve is an awesome touch and the reason I chose this over a camelback. The rigid back is also very nice, no collapsing under the weight of the water.

Rated5out of5byfromBest Water Delivery System I've UsedI have CamelBak and Platypus water reservoirs as well as this Osprey, and this one has the best water flow through the tube. The rigid internal frame is perfect for inside my backpack, which was the whole reason I wanted it. My other reservoirs would slide down and bunch up at the bottom of the pack, this one stays put. The wide opening is very easy to fill, and the handle makes it even more convenient. The magnetic clip for the sternum strap on my pack is perfect, no squeeze clamp to fumble around with, strong magnet does not easily come loose. I got this one for my son, I have the 100 ounce version too and love it just as much.
