Rated 5 out of 5 by from My favorite reservoir by far I 'm surprised by the number of negative reviews this thing has. It's by far my favorite hydration reservoir I've ever owned and I've owned a ton of them. The new closure is so much better than the large twist shut mechanism on the older osprey & camelback reservoirs. It's so much easier to make sure it's closed properly and won't leak, but the opening is still nice and big for easy filling and adding ice. At first I was a little annoyed that the top doesn't have a hanging hook, only a loop, but it was pretty easy to modify my hiking backpack to hold it. The loop is probably way less prone to breaking than the hook. I love how easy it is to clean, and I've been using it heavily for several months now and there have been no issues with build quality or durability. All the hose connections remain tight for me, even though I take it apart fairly often to clean and move between cycling and hiking packs. I love the feel of the bite valve compared to a lot of the competition out there, and the water flow rate I think is absolutely perfect. It did have a plastic-y taste when it was brand new, which isn't unique to this bladder. I put about a 1/4 of white vinegar in it, filled it up with water, sucked it into the tube, and then let it sit for about 30 minutes before emptying. Took care of it. My only gripe at all, is the one that came included with my Raptor 14 didn't include the quick connect so I had to buy that separately. Boo. That felt a little like a bait & switch, but maybe the raptor i bought was old stock.

Rated 1 out of 5 by from Not for mountain biking Terrible: 1) Water tastes like chemicals/plastic. 2) Out of the box, the valve leaked on my lap, and I could only suck in air bubbles, so I had to buy a new valve for $6. 3) The non-adjustable 45 degree bite valve makes it very difficult to get the valve in my mouth in a position so that I can suck water from it. Whose stupid idea was that? All bladders require an adjustable bite valve that can be set at 90 degrees--or more! 4) It takes one hand to hold the bladder, and it takes my other hand to squeeze the top to create an opening in which to pour water. Now, which other body part am I supposed to use to pour water into the bladder? 5) I'm tall, so for me the hose is about 2" too short.

Rated 3 out of 5 by from Cannot compress!!! I purchased this bladder for a 3-day hike of Mt. Whitney. Little did I know, the bladder cannot be compressed while in your pack without leaking over the top. On first use, I filled it up to max capacity, inserted it into my 65L Osprey pack, proceeded to secure my pack my cinching down all straps and, the bladder started leaking immediately. What is the point of a bladder if it cannot be squeezed without leaking? I was reduced to filling it up only half the rest of my hike. Do not use this product if you will be packing a lot of gear along with it, if so fill it only halfway.

Rated 4 out of 5 by from Easy to fill I like the opening on the better then the old version. I also like the quick disconnect on the hose. The water tasted very plastic the first few times but it's fine now.

Rated 5 out of 5 by from Wonderfully convenient !!!!!!!! The reservoir is very easy to fill and add ice to it. the quick detachable water tube being half way onlong the length of the water tube makes for quicker bladder swaps; I have one with water and one with energy drink, so that I don't have to dig down to the bottom of my reservoir pouch or pull the whole pouch out to connect the water tube.

Rated 4 out of 5 by from Good fit! Purchased it for long hikes and weekend trips. So far it’s doing well but looking forward to seeing how it performs on 3-4 day trips. Works well with current Osprey pack.

Rated 5 out of 5 by from Best bladder out there.. This is the best bladder I've ever used. Better than previous Osprey models and bladders from other major companies. I have had the original design of this bladder with the clip instead of the hole for at least two years and haven't broken it. How do all these people brake it? It's a plastic clip. Take care of it and it will take care of you. I ride very hard on both mountain and road bikes 4-6 days a week and this bladder has seen a LOT of use. Mine doesn't taste like plastic. It tastes like bottled water, which yeah has a bit of a weird taste to it, but just deal with it you bunch of ninnies. Or throw some lemon slices in when you fill it up. You're probably using this for biking or hiking or something that isn't a suit and tie dining experience, so stop giving negative reviews because you don't like how the water tastes. And if you just can't handle your water not tasting like it came from a tap in the Andes, then call Osprey and they will gladly do whatever they can to placate your whimpering. This bladder doesn't leak at all unlike bladders with screw-on lids, holds a lot of water, dispenses it quickly and deftly, is easy to completely disassemble for cleaning, and comes with the almighty Osprey guarantee. If you want to drink water to stay alive without carrying a bottle on the trail, then this bladder is five stars all day. If you want to sip Perrier in the cool shade while wearing linen pants and flip flops, then maybe consider another water delivery method.

Rated 5 out of 5 by from Easy to Use I bought the hydraulics reservoir a month ago and have been happy so far with its performance. Much easier to fill than I anticipated given some of the reviews, works well, and the 2L fits like a glove in my Osprey Daylite Pack. Loved the magnetic attachment to my pack. My only criticism would be that it doesn't have a built in mouth guard/cover. I ordered the cover separately, but am still struggling with how to more permanently loop it to the hosing.

Would the 3L fit the Osprey Tempest 20? 

Asked by: Jc2897
Hiya Jc2897, thanks for your question! Yes, the 3 liter fits in the Tempest 20! Personally, I would fill it with snacks... but hydration is probably more important. Hope this helps!

Can be used in just a regular backpack? 

Asked by: Joko
Thanks for the question! Yes, you could use your regular backpack, but you will need to make sure there isn't a lot of pressure on the reservoir. Also, you could potentially have issues with the tube length. Just make sure it is placed near the top and close to your back. Then thread the hose out the bottom of your pack, and route it to where you can clip it to your chest harness. Hope this helps!

I have the Atmos 65 and am planning to get this. I'm thinking of the weight when it is filled. I wonder if there is any drawback to getting the 3 liter and just not filling it completely. Why would one want the 2 liter if that is the case?

Asked by: JerryV
Great question! So, no drawbacks to getting a 3 liter and not filling it. The purpose of getting a 2 liter in any situation would be if your pack could not fit a 3 liter (inch taller and wider than 2 liter).The 3 liter will certainly fit your Atmos and you can under fill it to cut down on weight. 2 liters would best serve their purpose for smaller packs. Also, to get the best water flow, I wouldn't suggest having your bladder smashed in. You could run the risk of pinching the outlet. I hope this helps!

will this bladder, in either 2L or 3L work in my Gregory Z35 or REI Traverse 30?... or is it just meant for Osprey packs? Other recommendations for either/or of these packs would be appreciated.

Asked by: Rev Thom
Hiya Rev Thom, thanks for your question! Most 3L reservoirs will fit in the Gregory Z35, including the Osprey Hydraulics Reservoir. Sorry, I can't test the REI Traverse 30, since we don't carry it. Hope this helps!

Would the 3L fit in the Osprey Talon 22?

Hiya, thanks for your question! The hydration sleeve on the Osprey Talon 22 can fit a 2L or 3L reservoir. Hope this helps!

Will the 3 L fit into the Osprey Daylite pack? I assume the 2L would, but would love to go with the extra hydration if possible...Thanks!

Asked by: Bill919
Hey there Bill919, Great question! The Osprey Daylite pack and a 3L bladder will work wonderfully together. Happy hiking!

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

- + Warranty Info

ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty

When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.

Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.

Some Osprey All Mighty Guarantee FAQs:

What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.

What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.

How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.

What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.

Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.

Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.

JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.

All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
