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. The durable MPE reservoir material keeps water tasting exactly the way it should, and the magnetic bite valve keeps the hose secure when you're cruising up the trail.

  • Metallocene PE reservoir material is exceptionally strong, taste-free, and BPA- and PVC-free
  • Antimicrobial formula keeps mold and bacteria away
  • Wide-mouth cap is easy to fill and has a 3/4 turn for quick and secure closure
  • Front handle makes the reservoir easy to fill and insert into the pack
  • HydroStatic backer plate allows the reservoir to maintain a low-and-wide profile, preventing interference with your pack's suspension
  • Magnetic bite valve with included sternum strap magnet keeps the hose secure when hiking
  • Bite valve can be quickly closed with a 180-degree shut-off valve
  • Flexible 1/4 inch water hose increases flow for satisfying thirst quenching

"I need a Urologist"

  • Familiarity: I've used it several times

" Bladder Rupture" "Kinked Hose" Seriously...its true!! I did get about a years use out of my reservoir. After my first month of use the tube kinked and would occlude flow about every other use... Very Annoying!!! After one year of use the outer portion of bladder had about 3 areas that had leaking cuts in the bladder from inserting it into a backpack. Didn't realize Osprey only had a 1 year limited warranty on hydration systems.. Oooops!! I should have returned it within the first year and bought something else.. I learned my lesson..

Hello Friends,
Will a 3 liter hydration reservoir (bladder) fit a Ospry Raptor Pack 10?

Responded on

Hi bq of SoCal,

The specs on the Osprey Packs Raptor 10 Hydration Pack - 610cu in show a reservoir volume of 100oz so that will work perfectly with a 3L Osprey Packs Hydraulics Hydration Reservoir :) I just purchased the 3L and love it - let me know if you have any questions about it!

Cheers,

Cory

Happy Hydraulics

  • Familiarity: I've put it through the wringer

I’m pretty old fashioned when it comes to my water transport, but decided to give this water bag in a 3 L a try. I took this new fangled bladder out to Grand Staircase Escalante National Monument for a month of fieldwork and it actually did really well – no leaking issues from the body or the hose. It was really nice being able to drink water on a hike without having to stop to pull out a bottle every thirty minutes. The back of the pack is made of a harder plastic, making the overall structure pretty strong.

I made the mistake of leaving my pack and reservoir out of the tent and a small mammal chewed on the bite valve, but thankfully Backcountry sells a replacement (http://www.backcountry.com/osprey-packs-magnetic-bite-valve?ti=U2VhcmNoIFJlc3VsdHM6Yml0ZSB2YWx2ZToxOjM6Yml0ZSB2YWx2ZQ&skid=OSP0333-ONECOL-ONESIZ for Osprey Packs Magnetic Bite Valve replacement).

To conclude: I ended up really liking this product, but I do have one piece of negative feedback. The lid looks like if should work just fine, but the plastic bit connecting the lid to the bladder causes drag, making lid closure much more of a two hand job, meaning that sometimes lid screwing was a two man job.

Not to big - not to small

  • Familiarity: I've used it several times

3 L reservoir is just the right size... Provided enough water for my long/hot hike and doesn't consume much space in my pack(s). I felt it was easy to clean, no icky plastic taste. The handle and hardback make it easy to fill and keep shape. Another great Osprey product!

Great hydration system

  • Familiarity: I've put it through the wringer

Its a hydration system, what all could be so special about it right? Well, not entirely.

There are a few standout features that really sell me on the Osprey series. It comes with a magnet system to put on your pack's chest strap which is super convenient and keeps it out of the way. The handle makes it so that the battle at the sink is no longer a horrible losing war ending in at least one part of your clothing doused in water. And the back side of the bladder haw some reinforcing to prevent bangs, bashes and tears that are too common in ending the life of other bladders.

If you have any questions, feel free to give me a ring:

Osprey > Camelback Reservoir

  • Familiarity: I've used it several times

Bill Porreca recommended this reservoir for my replacement of my camel back. I'd have to say, this bladder is amazing. The feature of the handle really makes it easy to get as much water into the reservoir at the level you desire. The larger openings helps as well. Although, I'm not sure if this is available or not, but would like a sleeve for it in case my Osprey pack doesn't have one built in that I can attach to it.

Great little feature

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

This bladder was recommended by my gear head for an upcoming week in Glacier National. I picked up two new packs and a bladder for each. There a couple of nice features. 1st the handle supports the bladder nicely in a horizontal position for easy refills. You can actually do it one handed. The other feature I really enjoyed was the magnet clip on the mouthpiece. You can attach the corresponding clip on your pack and the mouthpiece will stay locked in. No reaching around to find the tube. It was right there in front of me all day. It was the envy of everyone on the hike.

I'm stoked this bladder worked out for you! For anyone interested in setting up an order and wanting to find out the perks of ordering through me, shoot me an email at skdavis@backcountry.com

One Flaw

  • Familiarity: I've used it several times

The one major design flaw in this system is the connection point between the hose and the bladder. Halfway through my second time having this out, the hose unattached and I lost most of my water and soaked my pack. I do however love the handle and ease of filling. The screw cap doesn't work as easily as camelbak's antidote reservoirs, but I do appreciate the way this bladder integrates with my Osprey pack.

Works like it should

  • Familiarity: I've put it through the wringer

This is solid bladder. I have been using this for years, not too much to say. It provides a good flow of water, the design is well thought out, I like the magnetic clip, it is easy to clean and dry, and the water never tastes funny. There you have it, this is a good bladder, I honestly dont know how they could have made it better, except for maybe maybe making it lighter, but that would sacrifice its durability, and maybe make the hose detachable.

Simple, reliable

  • Familiarity: I've put it through the wringer

I prefer this to the traditional CamelBak reservoir because it has a plastic frame that keeps its shape regardless of how full it is. The hose is nice (although not detachable, which is a little annoying). I'm on my 2nd one of these, it comes on every hiking/biking/camping/etc trip I do.

A Very Nice Rezy

  • Familiarity: I've put it through the wringer

Love the bite valve, easy to clean, no-nonsense, and doesn't leak. I've had many forms of hydration systems from several companies, this is the best. 2L is my volume of choice for day hikes and mountain biking.

Osprey Packs Hydraulics Hydration

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

I have been using Camelbak stuff which I like, but some of the features of the Osprey Packs Hydraulics Hydration Reservoir
take it to the top of its class: the reinforced plastic backing makes it less likely to get punctured when you are filling it from a stream; the handle and the magnet on the sternum strap. Good stuff.

It works...

  • Gender: Female
  • Familiarity: I've put it through the wringer

I found this reservoir to be a bit bulky for my Osprey day pack - it works well enough for bigger packs though. I haven't had any of the cap issues that others seem to be experiencing - I've used it several times now and it has worked perfectly for me each time. I really like how big the opening is, this is something I've had issues with in the past with other reservoirs. Overall, I'd say this a good product but maybe just a bit overpriced.

Watch out!

  • Familiarity: I've put it through the wringer

I really like this pack... when it works right. I've taken it on hikes and bike rides, and have been really happy to have it. But I've also had problems closing it on other trips. I find it really hard to tell whether the cap is actually on tight enough... There have been a few times where I THOUGH it was closed, put my pack on and then realized it was still slightly open, often resulting in all of my gear getting soaked... My laptop has actually been soaked a few times.... Its like the "Russian roulette" of hydration packs..

I have also had this problem. I thought there was a leak for a while but I guess it was actually just not closed tight enough.

Perfect fit for Osprey packs

  • Familiarity: I've used it several times

I've a few Osprey packs and this fits great. I love the hard back and the way they set the water hose so it is fixed going up on either side. The opening is nice and big, and I like the strong magnetic bag clip. Only downside is that it might be too bulky for lightweight consciences folks.

It gets the job done.

  • Familiarity: I've used it several times

I use an Osprey Stratos 24 for my day pack. Due to the Stratos design the 2L fits but the plastic handle takes up some additional room inside the pack. It is a little awkward to get in and out to refill without removing everything from my pack . It fits in my big pack with no issues. For the Stratos I ended up purchasing the 1.5L LT with the detachable hose.

Leaked almost right away

I rode with this maybe 2 or 3 times before it started leaking and it's unuseable. Very unhappy with this product.

Great Hydration System!

  • Familiarity: I've used it several times

Pros: Integrates nicely into my Osprey Aether 70! Love the magnetic clip that connects to my pack and the handle that is built into the bladder.

Cons: A little pricey
