Osprey Hydraulics Backpack Water Reservoir with Bite Valve - BPA-Free, Leakproof Hydration Bladder with QuickConnect and Slide-Seal - Compatible with Most Hiking and Biking Packs, Clear

Excellent works great

The twist valve broke in my hand, w/o any form of damage 3 months into owning it so now I'm unable to prevent leakage. Edit: they're sending me a replacement

The Osprey Hydraulics Backpack Water Reservoir has completely changed the way I stay hydrated on hikes, bike rides, and long travel days. Osprey's attention to detail and build quality shines through in every part of this hydration system, making it one of the smartest purchases I’ve made for my outdoor gear setup. Built for Real-World Use The design is intuitive and trail-ready. The wide Slide-Seal top makes it super easy to fill and clean—no more awkward spills or wrestling with narrow openings. It seals tight with no leaks, even when tossed into a pack with other gear. The rigid backplate keeps the shape flat and low-profile inside my backpack, which prevents bulging and makes packing simple. Durable and Leak-Free I've put this reservoir through the wringer—hot days, rough terrain, overstuffed bags—and it still performs flawlessly. The high-quality TPU material is tough, flexible, and doesn’t leave any strange aftertaste in the water. The quick-disconnect hose is a small detail that makes a big difference when refilling or cleaning. Smart, User-Friendly Design The bite valve delivers a strong, steady flow and seals well with a simple twist. The magnetic sternum clip is a brilliant touch—it keeps the hose accessible without it flopping around. Cleaning is hassle-free thanks to the wide mouth and detachable parts. Perfect Pairing with Osprey Packs If you already use an Osprey backpack (like the Daylite, Talon, or Atmos series), this reservoir integrates seamlessly into the hydration sleeve. But even in non-Osprey packs, it performs just as well thanks to its slim profile and robust build.

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.

This is well designed bladder that’s easy to fill and clean, and the quick-detach works great! However, it has a horrible plastic taste that persists despite many attempts to get rid of it, so is unusable for me. I have always loved Osprey bladders and have never had a problem with bad taste until this one.

This is a great hydration size for hiking. Even if you don't fill it completely because you don't need as much water it works great. The bladder is good quality and seems durable. I like that you can remove the straw to clean which makes it easier to clean and use. Fits multiple backpacks.

I purchased this bladder for Skiing to match my Osprey Kamber 16 bag. It fits very nicely but the only issue is while skiing I am moving frequently/falling and the top blue closing tab is not secure. It ends up sliding off the top of the bladder. This is because I use the Osprey red connection inside my bag that lets me hook onto the bladder. Leading to the top blue closing tab staying connected, while the bladder falls lower into my bag. The water has not leaked yet but it is a little concerning that everytime I open my bag around lunch it isn't always fully closed. I have used this on 3 ski days and it has happened every day so far. This could be mitigated by a stronger locking mechanism. I am not sure if other brands solve this issue but I hope Osprey can fix that in the future. Otherwise, this bladder is great and has served its purpose. I love the ability to disconnect the hose for easy refill and it keeps me hydrated on the mountain! I am sure it is much better suited for hiking or less intensive activities.

Worked great for 8 days in Alaska Had no issues with leaking. Great value. Like the hard back to help slide into the hydration pouch of the backpack. Has latest well, helped me stay hydrated on long hikes,

Très facile d utilisation pour mon sac à dos hikelite26. L insérer, le remplir, le nettoyer. Et semble très solide.

Absolut dicht, schlauch gut zu führen und zu befestigen. Einfach zu reinigen.

Perfect size for day hikes
