Description

A reservoir that won't fall apart fifteen miles from the trailhead. We really, really hate when that happens.

Need a water reservoir you can trust? Osprey put plenty of careful thought into its Hydraform Hydration Reservoir. A large, sturdy twist-off cap removes and tightens easily, and it leaves plenty of room to reach inside the reservoir for cleaning. A 180-degree bite valve shuts on and off with a simple twist, and the straw sticks magnetically to Osprey hydration pack sternum straps.

Great hydration system!

This is one solid bladder. I have used it extensively the past two years climbing, backpacking, and hiking. It's stiff structure is nice for packing, and it is just large enough for most quick day hikes. I have had no problems with the release valve and would recommend it!

Great hydration system!

Solid bladder

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

Haven't had it out too many times yet, but I plan on using everyday for touring. Seems to hold up well. Not super light, but solid materials. Magnetic clip is intersting, but haven't found a way to implelment it on my packs

Great

  • Familiarity: I've put it through the wringer

I have used my Osprey Reservoir exclusively for ski touring, and cannot be more pleased.

Rugged, easy to fill, comfortable, the list goes on. I've had it for nearly three years with no complaints.

Structured

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

So.... in my backpacking gear I'm looking for something light and versatile--and this aint it. I don't use it for backpacking.

BUT... in my mountain biking pack (an Ergon BC 2), I'm looking for a reservoir that can be put in and taken out easily... so I can run to the sink for a fill up just before a ride. Since I'm ALWAYS late, a minimum of fuss is a good thing.

In this capacity this bladder shines: because of its rigid structure, it's easy to fill under a faucet (it's not flopping around like a fish!) and it's easy to plug back into my pack after filling.

It's also particularly good for my kids to use when we hike together since their packs don't have dedicated bladder pockets and (again) the ease of use that comes from the structure of this bladder is "kid friendly" for my 10 year old. I mean... it's got a handle!

Not light. Bite valve is rather low flow. Love the magnetic clip idea but it doesn't quite work lots of the time.

With all the plastic on this thing, I bet it will leak sooner or later... but the rigidity it provides is "just the thing" for the particular way I use it.

Good and bad

  • Familiarity: I've put it through the wringer

My husband and I both use these, and generally like them. They fit nicely in our Osprey packs, the magnetic clip is really helpful, and they have never leaked.

Our only problem has been that it is very very difficult to take the mouth piece on and off. We literally have done tug of wars (one on the line other on the mouth piece) and still haven't been able to get them apart. This makes for horrible times in the morning and evenings of hikes. We might not buy again, as a result.

Leaks

  • Familiarity: I've put it through the wringer

I have to finally admit it... i hate this thing.
It has some great qualities. the rigid side is great for shoving it into a full pack. But the screw cap is not fool proof. I've had at least two occasions when it misthreaded or didn't get tight enough and leaked like a sieve.
Also, having used this for two years, I am not forced to replace the bite valve. The twisty, locking swivel has sprung a leak and no amount of twisting, finagling or cursing can stop this. I had to empty the bladder and abandon it last week in Torres Del Paine as it was leaking all over me and my camera at a drip per second rate. I couldn't get it elevated enough to not leak (bag content's pressure pushed water out the hose). So I was doing 10m days with a 1L nalgene... Lucky for me, that place is among the wettest I've ever seen!
For $30 bucks, i shouldn't have to replace parts in two years.

FYI: Go to Osprey's site and fill out a warrantee request for a new valve. They are replaced free of charge and referred to as "sheaths" if you just need the squishy part.

Responded on

Thanks. It's not the sheath that needs to be replaced. The leak is happening at the swivel.

Good Water Bladder

  • Familiarity: I've used it several times

I like this bladder. Used it when I was building barbwire fence in 95F weather, and it was plenty more than enough water to keep me hydrated. There are a few issues with it tough: when it is hot the PVC tube that goes to the mouthpiece absorbs heat so when you are taking a drink you get hot water for a spell until you purge it with cold water from the bladder. and I am not totally a fan of the formed plastic in it either.. because when it is fitted into my Aether 85 backpack it doesn't form to your spine because its too high up, and the piece is not removable.

I do like the ruggedness of it though! it is far from flimsy and extremely easy to clean.

Great product

I have several bladders and this is my favorite. It is very well made and has been durable so far. I primarily use it in my Atmos 65 pack, It has taken some rough treatment with no problem. It is easy to clean, overall a great bladder.

Works Perfectly

I use this bladder in my chugach 12 ski pack and love it . The had back and twist to tun on and off bite valve are awesome. I can not speak much to durability I have only had this out three days this season. The only problem i have had with it is the hose is too long to fit in the insulated sleeve in my pack but I think that is more attributed to it being such a small pack.

Pretty Good

Good solid product, only trouble was when it was below freezing the line froze up easily when water was in it.

Responded on

Try lowing air into the hose

Responded on

Yeah, back flow the water out of the hose. After you drink, blow air in lke redairline said or use gravity - hold the nozzle high above your head, squeeze the sheath and let the water backflow out of the hose.
Insulators work upt to maybe 25*. Below that, they're pretty useless.

great!

great product, love the wide opening for ice filling & the turn nozzle I can get a good drink

Not Bad.

Mine lasted two years which is pretty good for what I put it through. Not sure if I'll buy another one.

Love it!

I just got it and haven't gotten to use it much. No problems yet! It was easy to put into my Osprey Xenon pack and it is not too heavy at all. (I'm a weakling so that says a lot!)

I don't leave without it

  • Gender: Male
  • Familiarity: I've used it several times

This thing is awesome. I can't even compare this with my brother's camelbak, which started leaking on his last trip out. The magnetized mouth piece is really nice to have. It keeps your straw from bouncing all over when you're on the move, and you always know where your mouthpiece is going to be. Also, the nalgene handle and lid come in handy when filling this thing. I can't say enough good things about this.

I use this for hiking in several different packs. I usually got out for a hike once a week, and it hasn't failed me.

Osprey Hydration Reservoir

I like this reservoir quite a bit for running and skiing. The back panel support keeps it flat compared to other bladders which turn into tubes making them uncomfortable on your pack. Its also not necessary to have it suspended because of its rigidity. I have not had any leakage as previously mentioned but after good use, the bite valve is starting to come apart so it leaks there. Once I get a replacement bite it will be all set to go again. Also - the plastic is not durable enough for boiling water. Duh - right?

Leaking

Got this as a part of the Raptor backpack. The reservoir started leaking at the bottom near the seam the 5th. time it was used. Not impressed at all. My camelback is not leaking, and it is 4 years old!

Leaked with limited use, will return

Not a good product

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

First let me say, I love Osprey's packs. But this product is terrible. I've owned 3 and they all began leaking in the same spot, near the bottom at the seam. I started the AT last March 2012 with a brand new one (my third and last)and 9 days in near Franklin, NC it began leaking. I replaced in Nanthala, NC with a 2L Platypus and it lasted the rest of the trip with no problems. Furthermore, my dad, who was with me thru-hiking had the same issue with his, albeit his lasted until Hot Springs, NC. Also, 2 other thru-hikers we met had issues with leaking and had theirs in trash bags in their pack. They, too, replaced with a Platypus brand reservoir. The Platypus was the most widely used reservoir on the trail in 2012 and only one person I know of had an issue with the outside of his Platy delaminating and it subsequently sprung a leak, but he had had his for a few years. So between my 3 leaking Osprey reservoirs, my fathers 1 and two other AT hikers in Hot Springs, NC, that's 6 leaking Osprey reservoirs. I would not buy this product again and NOT recommend to others. Great packs! I will never not own an Osprey pack, but the reservoir is garbage!

the best

  • Familiarity: I've used it several times

We've bought knock-offs and CamelBaks and this is by far the best product. The internal support makes it much more comfortable to carry. The magnetic piece of the straw is just wonderfully designed. It sounds funny, but it's so easy to drink from this. This also has less of a plastic taste than other systems we've used.

Great hydration bladder

  • Gender: Male
  • Familiarity: I've used it several times

This is a fantastic bladder for your hydration pack. Easy to fill with great lid and seal. It has a bit of a frame to keep it in place and to make sure it goes in the bag easily. Not the lightest if you are real concerned about that but will last and the drinking nosel is fantastic and does not freeze in the cold.
