Everything works

How I use it: in our Deuter Kid Comfort II child carrier, and in my daypack. The tube is a nice length for these.

Filling: nice wide mouth, easy to fill with water and ice

In use: the bite valve works well (as most bite valves do) and seals tightly. There's an additional valve in the "head" that's useful for transport if you leave the hose attached. It tends to get compressed in the child carrier due to the weight of our son, and I haven't noticed any leaking. The detachable hose is really nice for transport and storing the bladder in the fridge before heading out.
Initially, there were a few times that I cross-threaded the top and it didn't seal properly, but I caught it immediately. It leaks like a sieve if you don't get the top on straight.

Cleaning: the wide mouth makes it easy to get my hand all the way inside if I need to. I don't put sticky things in my bladders, but I imagine if I did the quick release might be a little tricky to get totally clean. The little flip out arms for drying are a nice addition to hold it open, since the internal baffle makes the use of the CamelBak drying hanger difficult.

Summary: it works well, doesn't leak, is easy to clean/fill, and has a few unique features (quick disconnect hose, drying arms) that aren't strictly necessary but are nice additions. The lid isn't difficult to operate, but you should pay attention to make sure it's on correctly.

No leaks, but tricky to fill properly

It's a water bladder.... There is not much to discuss in terms of what your supposed to use it for and how you are supposed to use it.

Pro's: The end point connections on the flow tubes are much more improved when compared to previous models. I haven't had issues with leaking at connection points like I did with older models, and cleaning/maintenaince is exponentially easier to get done.

Con's: The fill cap for the bladder is a bit tricky to use. There is only one way to hold it, and only one way to screw it back on. Any attempts to deviate from this will result in a bath. After a few times getting "refreshed" you will figure out how to hold it, and it work well. No leaks inside the pack.

All in all, this bladder is easier to clean and maintain, doesn't leak as much as previous generations did, but takes a little extra care to fill. Not bad.

Great Reservoir!

I use this reservoir nearly every single day and am very pleased with it! I'm a little concerned about how to best clean it - it seems the tube won't empty completely of water no matter how hard I blow through it after using and detaching it- but since I use it every day I'm hoping that will help keep any bacteria at bay. I did find out the one I purchased at REI came new missing the folding dryer arms so I'm trying to get this from the company - so that may totally help resolve the cleaning/drying out issue. But I will say I am very pleased with this purchase! I've used it both for hiking as well as biking - I just switched to a recumbent bike and place the reservoir in a pack that hangs on the back of the bike. I've had no problems at all with either the reservoir, tube or valve leaking. I highly recommend this!

convenient and manageable

If you pay attention to what you are doing, it is not difficult to close the lid on a full bag without either losing volume or misaligning the lid such that it leaks. It is possible to twist the lid into the closed position without it closing correctly, but when this happens it is obvious because the lid is not flush with the surrounding plastic rim and handle. The quick attach hose is very convenient, easy to drain for storage, and allows me to more easily use a pack that has a small hose opening through which it is difficult to thread a mouthpiece. I like this system, I have three of them in different sizes, and I have had no problems with leakage. The drying arms work well if you take the trouble to manually compress the sides and open the bladder to air.

Great buy

I used this product on my 3 week road trip that included multiple national parks on the west coast. It fit well in my back pack and reduced the space that normal water bottles would take up. I will be purchasing another one soon. My only issue was that if you don't get the cap on perfectly it does leak profusely! Mostly an issue of human error but it did spill all over my day pack and I had to hang everything up to dry. It looks like it seals but if you don't get it locked in, it will cause a mess. Just tip it upside down before putting it in your bag! Besides that, it was one of my most necessary purchases for my trip!

Best reservoir I've tried

After trying a couple different brands, including Platypus, this is the reservoir I'm gonna drink from while trail running, backpacking, and completing military training.

The valve shut-off is much more secure than my Platypus, which dumped 2 liters all over the back of my Jeep because it came unlocked. The cap is easier to work than the zip on the Platypus, and the piece below the cap provides an excellent filling handle. Detachable hose is easy to get on and off, and the bite valve works flawlessly. The drying arms are a nice feature, as is the center baffle, which really does keep the water from sloshing around, even on dynamic, rocky trail runs.

Nice to see innovation that works.

couldn't do it without it...

I Love to kayak every week year round and my trips range 6-24 miles in a day. Summers in Austin are really hot (like 100+ degrees) so I have 2 reservoirs. I fill one with water and freeze it and fill the other with ice water. That way I can easily interchange them in my Camelbak on my trips. Some days there's lots of wind and wave and I cannot afford to put my paddle down to drink, but I can usually grab the valve with my mouth and drink all I need or at least flick it up with my thumb... and it never leaks. Don't know how I would make it without these amazing little reservoirs!!

What a reservoir should be

I bought this reservoir to replace a platypus bladder that leaked if the hose wasn't attached perfectly. I got tired of running out of water and having wet things in my bag so I decided to change over to Camelback's product. I wish I had done so sooner. The only edge I would give to my old bladder is that it was easier to fill with standard backpacking water filters because you could remove the bite valve easily and just connect the hose to the filter. A product that is watertight is more important to me.

Happy with my antidote service!

I ran into a bit of leaking with my antidote like many of you have noted. The fantastic thing about CamelBak products is the guarantee. Call customer service and they will replace the part causing you issues. I love CamelBak products but a huge reason I use their stuff is the service. I always get issues address right away. I have bottles from years ago; I get the bite valve replaced and keep the bottles. I am happy to say that my antidote no longer leaks since I got my replacement piece!
shayylala at REI on 12/12/2011

Best customer service ever!

Just wanted to add to the review I previously wrote - Camelbak responded in record time sending me not one but two additional yellow S dryer clips to help with drying out my hydration pack since the one I purchased was missing this. Has this ever been a HUGE help! Honestly I am using this daily and it's holding up great! And after receiving such great customer help you better believe I'll be purchasing more of these! Great company standing behind a great product. I highly recommend!

Negative Reviews:

Good when it works

Overall its a good reservoir, has a nice bite valve that doesn't leak when shut. it is very lightweight but this causes it to be flimsy and floppy. It is also a bit difficult to fill all the way up because you have to hold both ends of the bag to get it completely open, and this is especially tricky when filling from a water fountain or any where thats not a sink. I have used numerous Camelbaks in the past that i thoroughly enjoyed, but this one was a disappointment. On the second day of an eight day backpacking trip through the Rockies it started leaking. I love the convenience of having a Camelbak but this just made it un useable as it would soaked all my gear. It turned out that two of the other people with me had problems with the same reservoir. These leaks were in different parts too, one was in the connection of the tube another was a small puncture due to its delicately thin plastic and mine would just leak all over. It seems to me that the quality of Camelbak's reservoirs has gone downhill and i will most not likely buy any more of their products until they get this problem under control.

Bought three... they all leak

I really wanted to like them. I've owned Camelbaks in the past. Love the idea of detachable hose and baffle to keep the bulk down. Everything seemed well made. But then I noticed a pool of water at the bottom of my pack the second time out hiking. Couldn't figure out where it was coming from. I filled it with water and squeezed it but couldn't find a leak. I went out again and there was water around the cap and water around the valve. Figured I had a defective one so exchanged it for another. The next one leaked around the valve on my next hike. Also noticed the valve leaking when I squeezed it. Thought, well, I'll give it one more shot and exchange for a third since I liked the design so much. This time it leaked around the cap as soon as I filled it. I'm moving on and trying another brand. Sorry Camelbak. Thanks REI for you return policy.
mlhell at REI on 08/08/2011

Great except for that fatal design flaw

I loved this bladder - to bad is wasn't more durable. The quick release hose and the lock on the mouthpiece were great as was the big opening with a handle. I also liked the baffle that really cut back on shifting. Unfortunately the hard sharp edge around the opening (inside the bladder) wore a pinpoint hole that leaked after three uses. Softening or rounding this edge could solve this problem. Maybe a future version will address this.
alhazen at REI on 11/11/2011


I love the new design but when I used it for one of my hiking trips I noticed that the bottom of my pack was wet. I inspected the badder but there were no visible signs of a leak, then I tried to squeeze it a little bit and then there it was, the leak was coming from the new quick disconnect system for the hose and the bladder. Camelbak should revise the design for the quick disconnect.
Fishie at REI on 08/08/2011

limited use

Like some of the others noted a leaking problem.
Seems to leak under pressure where the hose connects to the reservoir. Used it twice in my Gregory 65 and ended up with a wet sleeping bag.
Admittedly the bag was tighly packed and cinched.
When used in my day pack (light and loosely packed) had no problem.
Would I buy another, no. Will I still continue to use older version camelback units, yes.

Flawed Lower Valve

The flatter concept of this water bladder is great. It gives you more room in your pack. However, placing a "quick" disconnect valve at the bottom of the bladder may not have been such a great idea because the pressure on the bladder causes the valve to leak. Recently, in just two hours, the bottom of my pack, including my sleeping bag, was soaked.
Dave at REI on 10/10/2011

Wanted to like this but.....

I was excited to try this and bought two. One worked well and the other leaked like crazy in my bag. The only thing that save my camera gear was a Mountainsmith Camera Cube (great item!). Exchanged it only to have the other leak too. Went back to the old model and have had no issues.
Midwest Chris at REI on 08/08/2012

It leaks...

A bladder really only has one purpose and that's to hold water. This one does not hold water, it leaks. It's completely useless.

REI should discontinue this product. It's extremely dangerous to be selling leaky bladders. It seems as though about 50% of them leak... way too many!
Boulder Hiker at REI on 07/07/2012

Leaks terribly

Stupid 1/4 turn cap leaks like crazy. Nothing like water running down your back because of a poorly designed fill cap that can't be tightened. Can't buy the old Camelbak design so I have to resort to a different brand.

Neutral Reviews:

unfortunate leak

(not sure why my choices for self description are limited to cycling. I am an avid one, but my use for this product was hiking/backpacking - review applies for many uses)

First off, I want to say that I've never had a problem with camelback reservoirs before, and will assume what happened with my new 70 Antidote was an anomaly unique to the one I purchased.
Everything about the new design is excellent, and improvement over the old ones. In fact I didn't really need a new one, but I wanted to reduce weight for backpacking, and my 100oz res doesn't fit ideally in my new backpack as well. I like the new low profile (flatter), quick open or "seal" design, and especially the tube disconnect.
Here's the issue (and why "seal" is in quotes): When the res is full, and under no pressure, no problems. But, when I compress my backpack when the res has over a liter (> 50% full), it leaks around the fill area. I'm not sure if this is a design problem - that the new 1/4 turn seal can't handle significantly additional pressure (I compress to the max for balance) OR just the one I got. Sooo.... I will exchange for another one, and retest.
In the meantime, I'll assume it was just the one I got, and for now give 3 stars. If the next one doesn't fail, I'll go to 5 stars. If it fails, it goes down to two (a decent product with limitations).

Does the job

The wide mouth is nice for washing, but the closing mechanism is a little finicky. My wife refuses to even try. I use this with a Stroke 9 and it works well, though the thickness of the closure is apparent in such a small pack.
