    Custom-fit suspension systems are Osprey's bread and butter, so it makes sense that the Hydraulics Hydration Reservoir is shaped with a rigid backer plate to prevent any interference with how your pack fits and carries. Additionally, the durable TPU reservoir material keeps water tasting exactly the way it should, and the bite valve keeps the hose secure when you're cruising up the trail.

    Just what I wanted

    • Familiarity: I've used it once or twice and have initial impressions

    I decided to get this reservoir because of the ease of cleaning and the rigid back. So far I'm very happy with my choice, the magnetic clip on the hose is great too.

    great bladder

    • Familiarity: I've put it through the wringer

    This is a great design improvement from the older Osprey bladders. I have yet to experience a leak, which was a constant problem with my old model. It also fits into every pack I have, including a 12L ski pack. My favorite aspect is the magnetic chest strap clip. Makes hydration so accessible.

    Great Design

    • Familiarity: I've used it several times

    I bought this reservoir to replace my Camelback reservoir and am super impressed by the design. The top loading system makes it easy to refill and also clean. Much easier to use than the screw cap style. Highly recommend.

    Easy to use

    • Familiarity: I've used it once or twice and have initial impressions

    Filling, sealing and carrying a hydration reservoir has been made exponentially easier with this thoughtful designed. The backing is a great feature for keeping it in the right spot and the magnetic bite valve is genius.

    Easy Design

    • Familiarity: I've put it through the wringer

    I have had a Camelbak hydration reservoir for as long as I can remember, and always stuck to it. I recently decided to give this guy a shot and I am forever changed!
    It is the easiest fill up possible, and locks shut quickly and painlessly as well. I also really love the backer plate, so it doesn't sag down in your pack which I have had an issue with if using it in a lightweight day pack.
    The magnet feature is bomb too, easy to know where your hose is at all times and stow it away easier too.
    Osprey took all these simple, mindless features and applied them here making this reservoir one of the best on the market in my opinion!

    Pinnacle in Hydration Reservoirs

      It is clear Osprey has given a lot of thought to their reservoirs. The reservoir is more stable in my pack then alternatives, it is easy to fill up and dump out due to the removable hose.

      It is pretty basic, but my favorite thing is the magnet. It is great to always know where the hose is and then be able to stow it away when not in use. It never gets in my way (i keep it on my sternum strap or sometimes shoulder strap) and is very reliable.

      Well Designed Hydration Reservoir

      • Familiarity: I've used it several times

      This advance design definitely improves the stability of the reservoir in the pack. Refinements such as the magnet connector and the quick release make operation so much easier. The new top flap opening is a better location and more efficient use of space, but the opening seems a little smaller than I expected. Super Osprey quality as usual. Bought two!

      Easy to use, slow flow

      • Familiarity: I've used it several times

      Very easy to fill up and attach to my Osprey pack. The magnetic piece kept the hose and bite valve from dangling around (though mostly forced it into my elbow). I still have to figure out what is the best way to secure the bite value while hiking. The one drawback is that the bite valve noticeably restricted the flow of water, making it difficult to drink. Instead of being able to take a couple quick gulps, it was more like several small sips.

      Drink more water, Live better

      • Familiarity: I've used it several times

      Recently picked up one of these for a backpacking trip. I hadn't used a reservoir in a while and had become so accustomed to just using water bottles. I had forgotten how much easier it is to stay hydrated while hiking when you can just suck on a straw that is conveniently placed in the center of your chest. I found myself drinking way more water on our all day trek to our camp. Do yourself a favor, leave the bottles at home, get yourself a reservoir and stay hydrated!

      Solid Reservoir

      • Familiarity: I've put it through the wringer

      Osprey makes filling up your reservoir even more streamlined by adding a quick release button on the hose so you can quickly disconnect the reservoir for filling and cleaning. The slide closure is also super solid and have never had any issues leaking. Magnet on the hose also makes it easy to secure hose while riding or hiking.

      Love this thing!!

      • Familiarity: I've put it through the wringer

      This reservoir is one of my favorite pieces of gear, it's super easy to use and has so many great features. I love that I can detach the hose from the bag, this makes refilling the reservoir quick and easy. The carry handle also helps a lot when filling the bag up in a sink. Overall I would purchase this product again and again!!

      Stay hydrated

      • Familiarity: I've put it through the wringer

      This is the best hydration system I have ever used. The quick release hose system makes filling the reservoir simple and convenient, no need to put your entire pack under the water source. The bite valve is also great, never worry about getting dripped on again.

      So great i bought 2!

      • Familiarity: I've put it through the wringer

      Such a well put together bladder, i love it! I love the multiple point connections that allow you to easily remove and refill the bladder without having to rewire the hose through your bag. I love the plastic back that makes it super easy to pull it in and out of your bag. Very high quality made and put together. This should last me years. I bought second for my girlfriend.

      New Favorite Reservoir

      • Familiarity: I've used it several times

      I recently bought a new reservoir after having a Camelbak for years. There are a few things that I specifically appreciate about it. I like that the tube disconnects from the reservoir so you can easily remove just the reservoir to clean or fill it. It's also great that you can open the top to fill and clean it. It makes it very easy to clean/dry. It is also easy to close.

      Best Hydration Reservoir

      • Familiarity: I've put it through the wringer

      I love the magnetic connector on the bite valve. It makes it easy to drink while bike riding. Its also an incredibly easy reservoir to clean. Make sure you get an osprey cleaning kit too. It makes cleaning even easier and you can use the brush to wash your water bottles too.

      Awesome Reservoir

      • Familiarity: I've used it several times

      The Osprey hydration reservoir is an essential to me when I am out there backpacking. It's a great hydration reservoir to use with just about any pack, but especially great paired with an Osprey pack! I toss it in the back of my Aether AG 60 and off I go. I have it in the 3L because I like to do a lot of weekend/overnight trips with it. It can get a little bit heavy when full. However, if you are trying to travel with as little weight as possible I would probably look into the Osprey LT Hydration Reservoir. Overall, awesome hydration reservoir and it does the trick for always keeping a few liters of fresh water right on hand for you for those multi-day trips.

      Drinking Water in the Mountains: Hydration Systems

      So being a hydration bladder guy, I have owned quite a few hydration systems. on a recent backpacking trip and I brought out all the ones I own and tested them up against one another.
      So let go through the candidates…
      the one I have owned the longest is the
      Platypus Big Zip 2.0 Liter
      The Platypus is a good system, but it falls short from being perfect.
      I had to add Bite Valve Cover, the Ergo Hydrolock & Quick link conversion kit.

      Like the large opening at the top
      The quick connect to the bladder
      All my mods

      You have to close the top manually before attaching blue lock or it will leak
      Bite valve leaks even with the cover
      I give it 3 out of 5 stars

      Vapur 1.5 Liter DrinkLink Hydration System
      The Vapur is a good system and I use it to drink Gatorade mix in water, it's great at that but it still has it's weak spots.

      The tube system is perfect
      Bite valve has a on & off that is a push pull system
      The connection to the bag is a quick connect
      You can switch out the hose with the super cap and use it as a giant water bottle
      Collapses very small

      All quick connections disconnects easily, sometimes with out pushing the release buttons
      When being used as a hydration bladder there isn't a way to prevent it from falling down the hydration sleeve/pocket
      Not as easy to fill as the others systems

      Best Use:
      As extra water storage at camp or on the move
      I give it 2.5 out of 5 stars

      The Osprey is pretty close to perfection. It has a huge opening for filling
      Quick connection and a on and off in the bite valve.
      Very light
      Has a carry handle
      Big easy opening & Once closed it stays closed

      The off and on of the bite valve turns, I prefer the push pull of the Vapur
      Should have come with the Bite valve cover
      This one ranks the highest 4 out of 5 starts
      So my choice of hydration system is The Osprey


      • Familiarity: I've put it through the wringer

      I got this in 3 liter and it is compatible with my Osprey Aether 85. Simple to use both filling from a faucet as well as purifying from a stream. the detachable hose makes hauling it out of the pack easier.

      Are you supposed to be able to refill this through the detachable hose, or is that simply to keep your hose in your backpack while you take the reservoir out to refill?
