OspreyHydraulics Backpack Water Reservoir with Bite Valve

Easy to use. It slips easily into a backpack because of the hard plastic back. And I really like being able to disconnct the tube when I'm moving it in and out of my pack.

This working great and holds water like it should . Took this in an all day hiking trip in the Grand Canyon and lasted me all day with two extra water bottle of but I have no complaints.

I used a camelbak for years and always struggled with leaks. It could be user error but I never had success closing the camelbak without spilling and there was always leaking when I would take the bag out to refill.This reservoir is super user friendly. I use it for long distance cycling and had no issues or leaks after 6 hours of riding.Things to note:-- When you first open it, the seal to open the bag is VERY strong. Be super careful opening it the first time as I bet it would easily rip. Once you open it that first time, there's no issue from then on.-- I modified mine to use the camelbak bite valve instead because I find this type to be very mold prone. It was a bit of a tight fit, but I was able to get the camelbak one on and never had any issues after that.

I’ve used Osprey bladders for years but they’ve made small tweaks to the design and it is not an improvement. The plastic closure is now very difficult to slide on and off, and the bladder has torn.

Top quality and easy to use and clean

I purchased this same bladder years ago (2018 ish?) and only just finally blew through it (my own fault, not a manufacturer issue). I didn’t even question purchasing the exact same brand. I love the new look and feel to it, my only 2 complaints are: it’s just slightly longer than the old one, but it’s not an issue and that the inner bladder has a “divider” which I can see making it harder to clean. I may purchase the osprey cleaning kit that has the thing that keeps it open to dry properly. Other than those, I like that the top really seals itself now even before you close it. I love the new flow options on the mouthpiece that allow you to select gradually open, all the way, or totally closed. It seems more sturdy than the old version and I’m confident it will hold up for years, just like the last one.

Great replacement water pack. Fills and seals nice and easy. Water flow is fine, love the locking/magnetic valve. Fits my osprey pack. Feels a bit expensive, but you can’t argue with the quality and design.

Bought to replace my 2 year old 2.5 liter bladder that came with my Osprey hydropack. Upgrade design handles on the bladder make it easier to hold while refilling. Updated bite valve makes it easier to stop and turn on the flow to the bite valve. And the ability to route the hose to either left or right side makes it easier to shorten or lengthen the hose when routing inside and out of the pack.
