Positive Reviews:

Wow what an upgrade!

I've owned Camelbak products over the years and have been upgrading packs and reservoirs as the technology evolves. I have to say this reservoir is the biggest improvement yet.

First off no leaks on either the hose quick release or the fill port. I didn't just test it at home, I took it on the trail too. My theory as to why so many others have had problems is that the first production run didn't get the tolerances right. That sort of correction isn't likely to be mentioned on following runs, which means there isn't likely a way to tell if you have an early leaky version just by looking at the box unless you have specialized knowledge. If it helps anyone, my box lists it as part# 8-00435. The item number is 90763, but that probably doesn't change as it's part of the UPC number. I would suggest looking for item number 8-00435 or higher. I could be completely wrong on this; just trying to give others something to look for. If however you do get a leaky one, just exchange it until you get one that isn't. That's the great thing about REI, a no hassle return/exchange policy.

Something else to consider if your purchase is an upgrade like mine was. The sizes are not the same as the Hydro Titanium reservoirs. A 70 oz Antidote is way shorter than a 70 oz Hydro Titanium. I had to get the 100 oz Antidote which fits in my Camelbak pack just right. The bonus is now I have almost 50% more capacity than before! Camelbak needs to make it clear there is a length difference so you get the correct size for your pack.

The dryer arms are a nice touch, and if you get the optional hanger, you'll see this is a great system. The only slight downgrade I've found is the baffle makes it harder to get your hand past if you want to wipe the far end of the inside of the reservoir with a paper towel. It's still possible, just harder if you have big hands like me.

One of the great things about a hose disconnect is it makes drying/cleaning the inside of the hose so much easier. First hold one end of the hose and spin it in the air. The centrifugal force draws most of the droplets outs. Then you simply run the optional tube cleaning brush through the open end a few times before hanging it up for a final air dry. Note: you can only run the brush through the disconnect end that goes to the reservoir. If you put a disconnect on the drinking end (different type of connector), you'll find the on/off valve has too small an opening to accommodate the tube cleaner. That's why I really like having the disconnect on the reservoir end.

BTW, if you like having both a disconnect and a right angle on the drinking end like I do you're out of luck as Camelbak currently doesn't make a right angle that fits into the disconnect. This is unless you shop for the military versions of the attachments. There you will find a right angle that fits into either the civilian or military disconnect. Here's a link:

The best option, but not without flaws

This is the best choice for hydration when you know you will need plenty of water. Not having to take a "packs off" break in order to get the Nalgene bottle out (I found reaching around very difficult) is a huge advantage.

However, this has one major design flaw. The tube that connects to the bladder is kept in only by a single yellow button. All that has to happen is for that button to get pushed, and *POP* out comes the tube. I discovered this the hard way my first day hiking back out of the Grand Canyon. With a full pack (I was carry about 60 lbs) there are sometimes going to be things pushing against other things inside, and something managed to push that yellow button even though the Camelbak was in its designated pouch. I had to unpack and repack in order to get the Camelbak out to fix it. Fortunately, very little leaked out. I believe the system is at least designed to close the hole when the tube pops out. But really, this is a big blunder in my opinion. It should be some kind of screw-in system that can't be undone accidentally. I know EMS reviews comments on products, so please pass along this to the Camelbak company, it is a serious issue.

Still, this is what I would go with, only because when it is working properly (which for me was 5 out of 6 days and on the day it had the problem, it was only that one time) there is nothing better. You just feed the tube through the designated hole in the pack and tuck it under the chest-strap while you're hiking. It also works great with powdered Gatorade. I was worried at first the powder would clog the tube where it connects to the bladder, but I never encountered that problem.

No more torpedo!!

I recently upgraded to this after using my torpedo-like Camelback 3 L for years...and after watching my husband save serious space in his pack when he bought one. The other design was functional, but this is great, as it spreads out and helps avoid more "dead space" in the pack. The previous model stuck out right in the middle of the pack so I definitely had left/right sides; now it's much flatter and I have more options when arranging my gear. The cap sometimes leaks if the bladder is filled too full. The previous 3 L allowed me to fill it above and beyond without any issues; with this, I can't go too full or water will spill out of the top.

I haven't had any issues with the quick release causing leaks, but after reading some of the reviews, I'm almost obsessive in checking the tubing after putting the bladder back in the pack. If there were a way to make the quick release a little less touchy (without eventually needing a crowbar to open), and maybe have the bag a little wider so it lays flatter, that would be fantastic. I have noticed a faint plastic-y taste if the water stays long (days/weeks) in the bag, but I think that can almost be found anywhere if something is left in there long enough.

I am definitely satisfied with the changes and hope the new design will do well for quite some time. I still need to find something to do with my previously used, still functioning torpedo-back...

Great Way to Stay Hydrated, Anywhere

The new Camelbak Reservoir is stellar, man oh man. It's design features make it super easy to use. A few details I will mention:
-It's lighter by far than previous reservoirs.
-Despite being lightweight, it is tough and has stood up to a lot. After weeks of use, still looks like it's fresh out of the package.
-The ¼ turn closure thing works really well. I was skeptical at first, I thought it might cause a little bit of leakage, but so far I have found that the seal is completely waterproof. Also, the simple ¼ turn makes it easier to open and close the reservoir when it is full of water.
-Waterproof. The thing is waterproof. I was cautious at first because of other reviews that I'd read, but even after many hours of use, the inside of my pack is completely dry.
-The detachable tube is useful because it means the tube can stay in the pack when the reservoir is filled. Also it makes cleaning a lot easier.
-The little bit of plastic inside the reservoir itself is possibly the simplest, but most useful improvement. What it does is it distributes the water evenly so that when the reservoir is on your back it rides more comfortably and easily.

This reservoir has performed really well for me. It's durable and easy to use– perfect for most outdoor activities. So far, it's the best I've seen of its kind.

No leaks, works great. Awesome redesign

I've always used Camelbak products, but my old-style reservoirs were getting funky. I was REALLY wary of buying the new Antidote reservoirs after reading so many complaints about leakage, but I took a chance thinking I could just return them if they didn't work out. Well, I wound up buying 3 of the 100 oz pouches for various packs, plus a 70 oz. version for a kids' pack. All have been put through the paces: filled completely, packed with other gear and used on mountain bike and hiking trips. No leaks whatsoever. I am careful to close the lids properly. You have to line up the arrow on the cap with the proper guide mark on the reservoir. I can't say a single bad thing about them, and it's not for lack of trying. The wide mouth opening is great. I can reach my hand inside for drying. (The 100-oz reservoirs have two chambers in the bottom portion, so I do hang those pouches for full drying, but I can easily reach in to wipe up the water that pools below the opening when the pouch is inverted. A great buy and I'd get more. I have no affiliation with Camelbak other than being a very satisfied customer.

Best Purchase for Our Last Vacation

My wife and I just got back from a week of hiking and camping in Iceland. We had a lot of good gear with us, but the one item we were most grateful for was this reservoir.

I have a Deuter backpack that is compatible with hydration units, and this fit perfectly in the pack. It holds plenty of water, the most important consideration.

Even when we were driving the main road to a destination, this item was sitting in the back seat with its tube up in front between us for whenever we needed some water on the road.

When you run low and need to fill up, it's a snap. Typically we filled up on water early in the morning or late at night when the temperatures got down to 35 F or so. So it would have been a major pain to have our hands getting wet while refilling this thing and struggling to close it.

Instead, this reservoir is easy to refill and easy to close. No worries about spilling nearly freezing water on one's hands while filling up!

My wife, on multiple occasions, literally said "this was the best purchase we made for this trip."
KyleGoetz at REI on 07/07/2012

An incredible re-design

Camelbak really got this one right! Many of the shortcomings of the previous reservoir have been addressed.
-The detachable hose makes filling the reservoir easy since you can remove it from the pack without removing the tube. In addition, the quick-release tube allows for add-ons like the the in-line filter.

-The built in "drying rack" allows the reservoir to be easily dried for storage or after cleaning.

-The new 1/4 turn cap is excellent! I used to struggle to open and properly seal the caps of the old-style reservoir but this new feature makes opening and closing the top a breeze.

-The center baffle does a great job of re-distributing the water across the back, making for better weight-distribution, a smaller form-factor and easier loading into the pack.

-The slide-in handle to hang the reservoir in a pack is way more convenient than the previous loop and hook system.

Overall Camelbak has taken what might seem to be a basic component and made it user-friendly in ways I never dreamed of. A great improvement to an already excellent product.

Best Hydration System Yet

The Antidote exceeded my expectations on all accounts. On day hikes, I found that it held more than enough water. I am an avid mountain biker, and the Antidote is perfect for long, bumpy rides where hands-free hydration is essential. I have used the Antidote on many different trips. So far it has not leaked and has proved to be the easiest way to stay hydrated. My only complaint is that the reservoir is rather bulky, however I suppose that it has to be in order to hold all the water. Cleaning is easy. I just empty any remaining water and toss the thing in the freezer. It keeps it cool for the next time and makes sure that no mold grows. I called customer service at Camelbak to ask about how to clean the bite valve (you can toss it in the dishwasher), and was amazed at how helpful they were. If you have any problems or questions I recommend calling Camelbak directly, they're very friendly. Overall, a very reliable, useful product.

Great water reservoir - on second try

I've used Camelbak reservoirs and day packs for years, and I always buy at REI because of the guarantee (and the dividend and great service, etc.) I have to have easy access to water hiking both in the SE and SW. My first Antidote leaked badly at the hose attachment point so I returned it for a new one. That one is water tight. I encourage anyone who gets a leaky reservoir to try again. The Camelbak folks must have a quality control issue here, but REI will make it right, and Camelbak will get the feedback. Never buy elsewhere! The design of this is a good one, lays flatter than my old Camelbak, easier to dry inside, nice not to have to remove the whole reservoir to refill. I just had to persist til I got a water tight one.
Trulyb at REI on 11/11/2011

Improving on an already great product.

I have been using Camelback reservoirs for many years now and have had great success with them. The new Antidote line even adds to the already high quality and reliability of previous models, while adding some nice features that are a must have.

My big complaint about previous versions was cleaning and drying them when I got back home. With the new folding arms that keep the reservoir open, they dry much faster and more conveniently too. The quick connect hose at the base of the bladder is nice with my katadyn water filter, I wish they would have included this feature at the bite valve too, so you wouldnt have to take the bladder out of the pack in order to access the quick connect.

Overall Im very pleased with the new features they added. Nice job Camelbak!

Negative Reviews:

Not a great redesign

As a user of the old style, tried and true Camelbak bladder (15+ years), I was saddened when I needed another bladder and saw the redesign.

Old style bladder has been practically bullet proof, no leaks, and still going strong.

Not so much for the new design.

My two cents.

Pro: The new design incorporates two small "arms" to help drying the interior. Nice addition, but not necessary. You can use a (coated) wire hanger, and placed into the bladder to hold it open. Hang upside down and voila. It is nice to have the built in drying arms tho. I never had mold in the "old and unimproved" model using this technique.

There is a new handle around filling port to help fill the bladder. Nice, but not exceptional. Per Camelbak customer service, the bladder needs to be filled lying down to achieve the full 100 oz capacity. Capacity also includes hose volume. I could not quite squeeze in the 100 ounces, but close. It is a bit awkward to fill the bladder on the trail.

The hose is quick disconnect type, so expanding, adding accessories, etc is an option. I am only concerned that this may be another point that may start leaking, so I am wary of this item.

New plastic is BPA free. A plus if you are concerned about this.

The cons.

Plastic bladder is a bit stiff, especially the hose. The plastic may soften over time, so this may be picking nits.

No method to directly fill bladder from a pump (Nalgene type threaded fill port, etc). Again, maybe I am too picky.

The real con. This design is prone to leaking. REI and Camelbak are aware of this. The leaks occur around the "eighth turn" fill port. It took me a while to figure out it was a leak, not just excess water.

If you can find the older style fill port, buy that bladder.

The new design seems to have flaws, with many reporting leaks. Obviously not every bladder will leak. Your mileage may vary.

Happy trails!

Leaks don't buy

I purchased four CamelBak Antidote Reservoir - 100 fl. oz. and each of them leaked. I used them on several occasions while hiking. Upon inital use I thought (echoing other users) that the leaks were due to human error, spillage during filling or just sweat. I followed the cleaning instructions to a T from the Camelbak website to avoid bacteria growth. I took a long trip to Caprock Canyon, where water is a MUST to find that some of the water leaked. This weekend I planned for another trip to Caprock Canyon and filled the bladders up to get ready only to find that the bladder with the hose attached to the quick connect valve leaked all over my new pack and sleeping bag. DISASTER!!!! I tested the other two bladders as well only to find that they also leaked in the same location. I air dried my pack which took hours and decided against my trip to Caprock b/c of the importance of water and fear of another wet pack. This is the only product I purchased from REI w/o reading the reviews but thought Camelbak was the best brand in hydration systems. Now I see many reviews echoing the same issue. I purchased Camelbak due to the brand quality and assurance of previous models but this quick connect hose system is cheaply made, very poor quality and renders the hydration system useless. I'm sorry to say that Camelbak has lost a customer (make that three - me, my father and my wife) to Platypus. It only takes one wet pack and ruined trip to turn away a customer. I suggest Camelbak recall the quick connect system. I have not yet returned the three bladders to the store but we will see how REI reacts to the returns, I hear good things so I am hopeful.

Great Ideas, Poor Implementation

I have loved Camelbak products for years. I have purchased their packs for my wife, myself, my four children, sister and mother. When the Antidote reservoir came out, I had to have one because it had so many great improvements over the older Omega reservoir (narrower profile, quarter turn cap, quick release tube and built in drying arms).

I love the idea of all the improvements. Unfortunately, the quarter turn cap is junk. The concept is awesome, but the execution is lacking. My old screw on Omega cap is easier to close than the quarter turn cap on the Antidote (that's sad). I returned the first one directly through Camelbak for a new one. It worked okay for awhile, but it is now difficult to turn.

I have found wetting the seal makes closure much easier. Camelbak suggested I smear Vaseline on the seal. I haven't tried that yet.

On the positive side, the thinner profile is nice. I like the quick release tube, although recently that has become difficult to quickly release. I have not had any leaks as others have had.

All the "improvements" over the Omega reservoir are great ideas. Unfortunately, there appears to be some quality control or design flaw issues preventing successful implementation. If everything worked as advertised, Camelbak would have hit a home run.
Michael Z at REI on 07/07/2012

It leaks

I have now owned two of these, I was convinced Camelbak wouldn't produce an item they hadn't tested fully, so I bought a replacement when the first one failed.

I'll start with the PROs. It holds a nice shape when full, and the after taste is better than older models.

CONs, same as the other posts. If you want to simulate the leak fill the bladder full and place it on a flat table and put a little pressure on it. Grab the rim of the lid and pich it against the ring it sits in, pulling the lid "off center". Now grab some paper towels and clean up the mess.

All of this happens in a full pack, pressure from gear and some object pushing on one side of the lid are likely. It seems in my case very likely leaving me to climb in wet gear twice now because when the pack was full and laying flat in the truck all my water leaked out.

I have found that loading the bladder once ready to climb it doesn't seem to be as big of a problem, but I prefer to prep everything the night before for an early start.

LEAKY, tube pops out

I am so, so, so incredibly disappointed with this bladder.

My old design bladder is 5 years old, gets used 4+ times a week and day hikes/backpacking on the weekends. It never leaked once.

I got this bladder with my brand new Camelbak Aventura backpack. I tested it out at home for a few minutes and didn't notice anything unusual - I attributed the extra water to spillage while filling. I filled it up and took off up the mountain.

When trying to gently adjust the tube, I ended up pulling it out of the quick link system. My entire 100 oz of water leaked right out, all over my backpack, snacks, extra layers, and my clothing.

Hike cancelled due to lack of hydration. $40 in gas wasted for there and back, a couple hours of my time and I had to go home with wet pants.

The inside pocket for my reservoir was soaking wet from the leakage from around the fill opening.

Terrible design flaw. When I called Camelbak, they were helpful but are just sending me a new reservoir. I don't need a new one, they need to redesign the whole thing.
Subiedriver at REI on 02/02/2012

terrible product....

This is the worst camelbak product I have ever owned, and should never have made it to production. I bought one for my girlfriend, and immediately it leaked. I checked the cap to make sure it was tight, then tried to move it to another position and it popped off, spilling water everywhere. everywhere I tried the cap, it leaked. I traded it in at REI for another one, and it leaks the same. This time I hooked the hose up to it, and the bite valve also leaked... I liked the lower/wider profile than my old 100oz design, so I tried to slip it into my pack and the hose popped off 3x in a row. This product is very disappointing. If they put half of the time they spent designing the flashy appearance and packaging, they could have made this bladder function correctly.

On the other had, I have a 100oz resevoir that I bought from camelbak 4 years ago and it is still in service, still works and tastes great, and has never leaked a drop. boy how their quality has changed...

Leaky bag after just a couple seasons

We have four of these in our family lineup for hiking and backpacking. After two seasons of use, three of the four bags have sprung pinhole leaks in the body of the bag. First time it happened I thought maybe I just didn't tighten the closure. After the second time of soaking everything on the inside of the pack (and my butt) the problem was revealed with a pinhole, dribbly sized leak in the lower third of the bag, on the face, not the seam. I whined to the family during our next hike and my kids told me to suck it up since they had been dealing with a wet butt for months on our hikes. Sufficiently shamed, I checked theirs and same problem with a pinhole leak on the face of the bag that was small enough to give a constant dribble.
I thought we would get a little more mileage out of these than a couple seasons. And then you can't even recycle them. I know that REI would take them back but it just seems too wasteful to me.
JGZ at REI on 08/08/2013


The ol Camelbak was truckin right along, untill a few months after I bought it, and it slipped an o-ring or something. O-rings slip, that's fine, but the annoying thing is that first of all, they're not a generic size, so you have to spend 40 times as much as you should to get the part from Camelbak, and even worse, the detachable hose idea is just a bad one. It used to be that you just jammed your hose into the resevoir itself, and whamo, it worked. All the time. But now we have this bizarro detachable hose dealie that, as far as I can tell, serves no practical purpose whatsoever, other than to slap some whiz bang piece of junk onto a functional system so users think they need to upgrade. DON'T. Camelbak has increased the complexity of a system which seems to have declined in quality, so if you buy it, you can look forward to 5 months of functionality, then you may as well trash it.

Stay away from this bladder

I was in the Army for seven years so camelbak is not new to me and I used to be a great fan of there products. I was excited when I saw that they had a hose that was easily attached to the bladder to make filling more convenient however the only thing that the new attachment did was cause me headaches and heartbreaks for 450 miles of my trip it constantly leaked and kept my back and butt wet I wish they still sold the old model but it seems they have put this horrible design on all there bladders currently I am finished with camelbak but if they bring back the old design I will give them another shot but in till then I will stick to a different bladder

My bladder started leaking the very first time! At first I thought it was just residual water on the outside, but this past weekend, I purposefully wiped down the reservoir before I put it in my bag and sure enough when I arrived at the trail head and threw my pack on, my shirt was wet within seconds.

Very disappointed in this major design flaw. At first I thought it was merely a fluke, but after reading reviews, I know I'm not alone in this issue. And it's a serious bummer that it appears that Camelbak is not doing anything to offer a new style of reservoir that won't leak! I hope they fix it soon, so I can stop hiking with a wet shirt from minute 1!!!

Neutral Reviews:

Not a fan of the new design..

I was impressed with a few of the new features, namely the 1/4 turn opening & the baffle on the inside. However, I feel like the plastic area around the opening is unnecessarily bulky, and now that I've used it on a few trips I don't feel like the baffle actually does much. I could hear (& feel) my water sloshing back & forth on my last trip, especially across a talus/boulder field. My main issue is the new "quick disconnect" feature. I had a real "oh no!" moment on my first trip with this bladder when I felt water dripping down my back, & stuck my hand down into a pool of water in the water bladder compartment of my pack. I examined for leaks, & (thankfully) found none. I finally figured that the "quick disconnect" had disconnected when it was squeezed between my pack & my bear canister, and leaked all over the place. Though definitely better than a hole, still not the best. Overall still a good bladder, and definitely convenient to use, but with all the new changes I think I will try out a different brand next time.

Good design, but leaks

I got this reservoir with some reservations after reading many reviews saying it was leaky. The first few times I used it I didn't notice any leaks and was quite happy with it, but when I tested it more and put it in a plastic ziplock to check for leaks, there was a small but consistent leak at the quick-release hose attachment.

I was disappointed about the leak, because I really love that this reservoir is slightly wider and has a baffle inside so that it doesn't bulge out as much, making it much easier to get in and out of a pack. I also liked the drying arms, and the bite valve provided good water flow. But in the end, I returned it because I just didn't want to risk having it leak in my bag.

Good but a little leaky

I took this bladder day hiking on a recent vacation to Costa Rica. The capacity was great - I never had to refill all day. Unfortunatley, if I didn't remember to lock the mouthpiece, I would often have problems with it leaking when I set my backpack down. On the airplane, on a bus, on a trail - I'm quite forgetful, apparently. I would prefer the mouthpiece to be a little stiffer or something so that putting it down didn't equate to the mouthpiece opening and creating a puddle.

Has its good and bads

I love some of the features of this bladder such as the valve on the mouthpiece and the ease of removal of the tubing. I don't like the way the tube seals itself after removal. This makes drying the tube after washing very timely because it doesn't allow airflow.

I like it but mine was defective

Hiking, backpacking, mountain biking. I really like the warranty...lifetime. I'll send it back to Camelbak and get another. I'll likely use Camelbak bottles instead of bladders when I need ironclad reliablility. I've had too many bladders fail. I'll continue to use bladders for mountain biking.
