I had it complety full of water and I dropped it from about three feet, when I picked it up I carefully examined it. It was in perfect condition. I highly recomend this to any one who is hiking with a full pack. It is very durable.

If you have the room in your pack, go for the 100oz..why? It will bairly add any weight(unless full), you can always decide on how much water you want to bring. And its the same price as the 72oz. Seems like a no brainer. Opening the cap can be a pain, but its nothing to cry about.

This in my experience is the best Reservoir out their. It is simple and effective. I have had experience with many other brands and have had/seen many problems with leaks, rubber taisting water, faulty lids, etc. and have never had or seen any problems with this product. The insulated tube (sold seperately) is also a very worth while investment. No more warm water the first couple gulps!

perfect size for a long day hike, and with a water purifier you are good as long as you can find ground water. The only complaint is i wish the lids were different, they can be tough to get loose. still 5 stars.

Good durable reservoir that eliminates the need for carrying a bulky heavy nalgene or other water bottle. Can be used for a variety of things from a hydration system to a shower unit and broken down to use for a splint. Make sure to keep it clean and have fun!

Without a quick release valve it’s a pain in the rump to refill on the go but it sure takes a beatin. I’ll take quality over convenience any day.

I have the 3L version. I would never go with a smaller reservoir; there's no reason why you can't just fill the 3L up halfway if you don't need the full capacity. I have been using the same bladder for everything for about 6 years now and it still looks and functions like it did when I bought it. I have been taking care of it, making sure to wash it out right after I use it, as well as letting it air dry before I pack it away. I had a friend who did not do this and the bladder grew mold after being stuffed away full of water for several months. Moral of the story: don't be lazy and you will have a great hydration reservoir for a very long time.

Water tastes like water when coming out of this reservoir. However, beer tastes like carbonated plastic when coming out of this reservoir. And the bladder retains traces of that taste for about 5 uses later. Moral of the story: don't be an idiot.

I have lost numerous bite valves due to them being ripped off especially the ("shut-off-able" 90 deg one) for obvious reasons. I like the 90 though so I micro zipp-tied it on. haven't lost one since. wouldn't be a bad idea to carry a spare bite valve, the whole hydro pouch becomes pretty much useless if you loose a mouthpiece. PS the 100oz is a must.

I have used many others,but the camelbak omega h.t.is the best out there, this is my 2 one, the first is still working just fine,but for my new pack I wanted the 100 ounce.

I love this bladder. My pack has a perfect sleeve for it and the durability along with the ease of cleaning makes this resevoir my favorite on any trail.

This was my first hydration bladder and I have to say I really like it. The opening is really big so it's super easy to fill without making a mess and it's easy to wash out and dry. With the tube trap and hydrolock the bitevalve stayed in one place and didn't drip at all. Very convenient hydration for my hiking trips.

I use the 100oz bladder for any outdoor activity, most recently on a thru-hike of the Long Trail in VT. Most people use only the 70oz because it is a bit lighter and water sources are usually consistent. However, I kept with my 100oz because of several reason: 1. I could fill up with water in the evening, cook, clean, and have water for the morning, leaving 1.5L left for the trail, not needing to refill again in the morning. 2. If water sources were scarce, I could carry the extra water to bypass the less than pleasant standing water sources. 3. 100oz is big enough to rig up as a shower system with the hydrolock valve and have a nice shower every couple days.

Overall this thing performed beautifully. Always able to have a sip whenever I wanted. Great for consuming Clif Shot Blocks or GU while moving down the trail. Easy to use with a water filter or AquaMira drops (used both on the trip). Only problem I ran into is when leaning forward, putting pressure on the bladder stuffed between my back and the gear in my pack, it would SLOWLY begin to drip. Remedied by using the hydrolock valve. Not really a problem at all, but it was something I did notice.

I dont use a resevoir any more. But when I did, I used a 100oz. No complaints, worked as advertised. In cold wx blow the water back out of the tube to prevent freezing.

CamelBak reservoirs are superb. Yes, there are others that are good (for example, Platypus, of which we own three) and even as good. But for my money, I'm sticking with the standard. I've been using them for a dozen+ years without any issues. The 100 ouncer (3 liters) is our favorite for hiking and backpacking. Good quality, lots of wonderful accessories (such as the Hydrolock--I prefer the non-Ergo version) and a lifetime warranty. What more can a hiker want? Perhaps more days off from the grind at work to reach those summits on hot days.

I have the 3L version, and i take it on every hike and backpack. 5 years and no signs of wear. It is so great to be able to drink on the go. The biggest advantage of a bladder over a bottle is that it fits in the sleeve of your pack right up against the frame. The advantage is that water is the heaviest thing that you carry, and you want the heaviest items closest to your back. This reduces the torque on your pack and creates a more balanced load. Therefore, your pack will feel lighter. If you are even considering getting this item, get it. It is one of the least expensive pieces of gear that I own, yet easily one of the most important.

Antimicrobial and a lifetime warranty. You've got compatible packs etc., so why not?

The CamelBak is a pretty cool reservoir for pretty much any activity that I do. You can grab different accessories for it for different conditions, and if you get the 100oz. you have all the water you will need for a day or 2 on the trail. The lid on mine is really hard to open, and I know that lots of people have this same problem, but I just think of it as this: If I have troubles opening it, water has troubles getting out of it. I have dropped it, stepped on it completely full, and done numerous other abuses to it, and I still have it in almost perfect condition. Super easy to clean, except my hands don't fit in it like some peoples do. The thing that I feel would give it 5 stars is if CamelBak included a Hydrolock with the bladder, because it has a bit of a problem leaking out of the mouthpiece at times, drenching the front of you.

I've had it for more years than I can remember...maybe 6 or 7. I've only used it for water and its been great. No weird tastes, no problems with the hose/valve. Would highly recommend the 100 oz - you can always but 70 ozs of water in it if you need less!

I have the 100 oz. bladder and it is supreme. You can fit it in any pack just by not filling it all the way and it is completely indestructible. I have used it on all day backcountry ascents and descents, and alpine climbs mid-summer in the Colorado altitude and heat. Perfect hydration option.

I first purchased a 50 oz. bladder and soon found out that it just wasnt quite enough and forced me to have to carry a nalgene, which Id rather not do since it takes up more space in my pack. Im more a minimalist so the upgrade to the 72 oz (for only a couple extra bux) was well worth it. The first one I owned started leaking around where the tube connects to the bladder after only being detatched twice for cleaning. I figure this was simply a manufacturing flaw out of the batch that I recieved (first one purchased last year). I have detatched the tube on my new one several times just to make sure it was not going to give me any problems like the last one and it has held up fine. You got to expect at least one bad product from every assembly line. However, these bladders are the greatest. I have put water in these bladders with a little ice and left them sitting out directly in the Louisiana scorching sun for hours on end while fishing and my water stayed cold. It stays cold in every environment Ive used it in. The water tastes great, leaves no odd or plastic taste, and makes carrying enough hydration around a breeze. As stated, Id definitely go with a 72 oz over the smaller ones cuz you dont have to fill it all the way if you dont want to carry the extra weight of the water you wont use on short trips, runs, etc. I can't say enough great things about these bladders, not even after having a faulty one.

ok, so I'm an ol school bushwacker from Louisiana who always thought these things just didn't look as kewl as a good ol canteen out on the trail. also I have heard people complaining about bladders busting on them and soaking their gear. I always thought that was a sad story and poor excuse for 'looking cool' in the outdoors. Well, I decided last year to plan a hike thru the AT in 2010 and started gearing up. After checking out a video @ Backpacker.com where a guy runs a filled camelback over with a SUV I figured this might be worth a try. I was glad I made the purchase of this bladder and could care less how ridiculous I may look to my friends with it's tube running out of and dangling from my pack. Heh, my friends call it my colasthomy bag, but I think they're just jealous cuz I'm the only one with water every bit as kewl as it was when I filled it even after its been set directly in the sun. No joke, this thing can not only take a beating, but even placed in the direct sun of a 100+ day in smoldering Louisiana my water stayed very cool (aside from the obvious amount that stays trapped in the tube if you don't blow it back into the bladder after sipping). And to top it all off, to my amazement was how much like water my water really tasted coming out of this thing. No funky plastic taste or nothing...even tastes better coming out of the bladder than out of the tap...like it's an improvement. I could NEVER see going back to using canteens again...I can't now imagine an outdoors adventure without my camelback. From extensive reviews I have read I doubt I would ever purchase a bladder from anyone but camelback. Some people complain about the opening being hard to open up...I dunno bout that....I mean it even has a grip for unscrewing that enormous hole that I love...I think some people just need summin to complain about...

If you're curious or have had a bad experience with another brand of bladder hydration then I suggest you give this one a try; you'll love it!!

also, the hydrolock and cleaning kits are very convenient if you have one of these. I didn't notice any issues with leaking before I installed the hydrolock, but at the same time I didn't have the bladder long before I installed the hydrolock so...

I have had several camelbak's and was a fan, but my last trip (70-mile UL Solo) has taught me to hate camelbak and become a Platy fan from now on. In my three day trek, the hose pulled away from the bladder 4 times letting 3 liters of water fill the bottom of my pack soaking all of my gear. i could not see how this would happen 4 times, i did nothing different in packing than i always have done in the past- even when the tube was attached, if slight pressure was put on the bladder, water still leaked from the bottom. Maybe this is due to overuse of the bladder but i have never once ever had a drop of water come out of my platy. think twice before purchasing this- it will make your life miserable.

2 problems
I'm on my 3rd nipple/rubber bite valve. They keep getting torn rock climbing. I have a locking valve on mine which is essential as I keep ripping the things in the 1+ year I've had it.
Also the cover is an absolute pain to remove. It takes a lot of strength and patience especially on cold mornings to open it up.
Other than that, yeah it works.

I purchased this hydration bladder to replace another one I was struggling with. Previously I was struggling to get enough water into me, but with this bladder I am able to hydrate easily and haven't had a single problem.
Be aware the tech specs says it's a locking bite valve, however mine did not have a lock when it arrived. Luckily I'd had also bought the Hydrolock which is fabulous.
I highly recommend this bladder.

I have the 100 oz / 3 L verson and I love it. It works in all of my packs and the versatility makes life a lot easier. It's durable, it hasn't leaked, it's easy to fill, and there isn't an after-taste. The tube is long enough so you can improvise your set up if need be and there is a clip on the top near the refill cap so you can hang it upright in your pack. Water only comes out when you bite down on the valve and if you are worried about germs, it is treated with an anti-microbial coating. I would recommend buying the 100 oz. version because you don't always have to completely fill it up is space is limited.

I bought this as a replacement for my husband's other reservoir which just worn out.

I own one of these and an MSR bladder they seem the exact same. a quality bladder is a quality bladder. I am not a huge fan of the on off switch/ have not found a good reason for it yet.

I finally caved and bought my first camelbak about a yr ago. I like it overall but two negatives: it does give the water a funky plasticy taste and this doesn't go away- it's not horrible and I can deal with it. The hangar clip broke the second or third time I used it- the plastic is too thin for the weight of 3L of water. To "fix" it I just drilled a hole in the remaining plastic and used a wire tie which works fine. And of course they're not usable in colder temps as the hose will freeze up.

Well worth the price, I haven been using it for two years on numerous hikes. 100oz is alot of water and its pretty easy to clean. I would get an ergolock just to be extra safe so no water leaks

Huge opening makes cleaning super simple, but my tip is to just keep it in the freezer when you are not using it as this prevents bacteria and fungal growth pretty darn well in my experience. No complaints. It's never leaked or failed me in anyway. No more bottles, hydration on the go!

I use my 3L for backcountry skiing inside my pack. I blow back on the tube every time so it doesn't freeze. When I get home, I dry it out by hanging it from the tube/bladder attachment crotch so that the mouthpiece hangs at the bottom of the vertical tube. It dries in a hurry this way; I hang it from a coat hanger.

Once it's dry I put it in the freezer until I need it again. My girlfriend says I'm stupid and that since we live in Colorado it'll be dry enough to avoid excessive bacterial growth without freezing it . . . but I plan on using this thing for the rest of my life, which will hopefully be several more decades of skiing and mountaineering and good stuff like that. She might be right though.

No complaints thus far, 10+ days of skiing Berthoud Pass. Tastes like water. I won't be putting anything else in it because I know better. If it breaks I'm going to be taking advantage of the warranty.

I have tried two different bladder brands before this, and both made the water taste horrendous, even after cleaning and lemon-juicing. The Camelbak does not have this problem. It is virtually tasteless, the way water is supposed to taste.

This is a well made and tough reservoir. I love the wide opening for filling. It's good to have a large bladder even if you don't fill it all the way up.

Great asset for long treks. Holds a lot of water, so fill it up!

liked it at first, until i found wet spots from little pin holes around the top. beside that the lid is pretty tough to open. i would suggest that if you want an easy to fill bladder that rocks get a platy. big zip.

I love my camel bak. It works great and hasn't leaked yet. The bite valve is awesome and never leaks. Go with the 100oz. and you will not be disapointed.

I absolutely love being able to carry 3 liters of h20 at one time; God knows it was a lifesaver when I went on a 22-mile hike in one day. I refilled once at high enough altitude to not have to filter the fresh mountain water, and the refill lasted the remaining 10-12 miles of all downhill.

The only thing I would change is having the drinking hose come standard with an "on/off" valve, like Nalgene brands do. Occasionally I felt a few droplets of water down my leg when hiking.

Otherwise, you can't go wrong with the name or the price of this product.

Filling and cleaning has never been easier! You simply can't go wrong with Camelbak!

The bladder is nice, strong, bacteria-resistant, and lightweight. However, the cap is really annoying. It's nice that it’s very large (for easy cleaning and adding things like ice), but it is extremely difficult to tighten correctly. You have to really crank down on it so it doesn't leak, but then it is really hard to loosen again. Not fun when your fingers are cold, I can tell you. It's hard to twist because of the way it is recessed, so you have to use your fingertips instead of your palm.

Camelbaks are great and easy to use. I did fork up another 6 bucks and bought the valve which helped to regulate water flow but otherwise great product. Like with any other of these reserviors, you will have some slight rubbery after taste but not harmful and goes away after mulitple uses.

Works great. I really like the wider opening. Makes it much easier to fill and clean.

After owning a nalgene hydration pack that broke and leaked so easily, this is like heaven. This camelbak hydration pack is worth every penny, plus more. It is sturdy and I never worry about leaking. Yay!

Big mouth is easy to fill. Cap ring has a tab which allows you to hold it level under the faucet or hose. No problem filling with ice cubes for those long hot Texas days on the trail.

I have 3 hydration backpacks and this reservoir is the best of the 3. I prefer it over the others because this one is more flexible, resists bacteria and is very simple to use. I've tried others that are clear plastic and don't bend or stretch as easily as the Camelbak. Also, the bite-valve is better than others. Some bite-valves are larger and have a "lock" or "on/off" ability which makes the valve larger (and harder to fit through holes) and confusing to use. I would recommend the Camelbak Omega HydroTanium Reservoir to anyone who wants ease of use and long-lasting durability.

great size wasn't too heavy when filled all the way up and lasted the whole day.

So this bladder is on the smaller side but its perfect for a 5k run, quick hike or bike. It keeps you hydrated long enough to feel like you actually accomplished something so drink up!

Definitely the way to go. Might freeze up at higher elevations or in colder temps, but awesome for hiking.

I've been using Camelbak reservoirs for years. I have the 100oz in my H.A.W.G. pack and have a 70oz that I used in my old day pack. I only use water in mine, as I'm not good about cleaning them after a long ride or hike. Never had a problem with funkyness. Mine always seem to stay together good, but I've had a friend accidentally disconnect the hose on a full one while on the ski hill, didn't make for a very fun day for him. So check your connections often. I don't like the bite valves without the Hydrolock accessory as mine always seem to leak when in a packed bag, biking with a full pack puts alot of pressure on the reservoir and it squeezes the water out at a trickle. Haven't used other types of bite valves on other brands so I'm not sure if they are any better. Otherwise this is a great product.

I was very pleased with the new camelbak, but in retrospect I should have gone with a bigger size. 50 oz seemed like plenty at the time, especially because I wanted to save a dollar or two. I would buy the biggest size available if I could do it over again! If you're worried about the weight, just don't fill it as full.

Nice and durable, no spilling and easy to clean...all you want in a reservoir. If you plan to use it in the winter it would be a good idea to get an insulator for the hose or be sure and get all the water out, it will freeze and potenitally break the nozzel

If you keep the tube in the freezer it NEVER goes moldy ... Gatorade and beer - no problem!

I have found just cleaning the bladder with warm water and an antimicrobial dish soap and then letting it dry works great. I am a scout leader and have used for several years with no problems. I like the lock. When you throw your gear into the back of a truck or van with gear from15 other scouts somethings your bite value get smushed between packs and without the lock you arrive for your hike minus water and then have a large water spot to clean up.

It's a really great reservoir. holds 3 liters of fluid! I like the flavored tablets that Camelbak are offering to help give the water a new taste.

I purchased the 100ml bladder for a trip I took to Peru and it keep me hydrated all day. Never ran out of water. Was hiking full days and was so thankful to have purchased the largest one.

This is bladder is great. The 100oz nicely into my day pack when full and stays cool without any insulation. My only complaint is that it is difficult to open.

Filled it up and never managed to empty it in one day during my recent trip to Las Lenas Argentina to ski despite vigorous skiing, some hiking, and long traverses with poles on the way out from the backside. Didn't notice the weight difference between it and my 72oz. reservoir. Replaced the standard tube with the insulated type with bite valve cover. Carried it with the tube zipped into my North Face backpack's shoulder strap and never had it freeze despite some howling cold winds and subzero temps.

I'm happy with the 70 oz size, anything larger would be ok, but this a good replacement. It is great for longer runs of 10+ miles. It is also good for the little ones, my 2 year old daughter can drink from it with no problems. It was worth every penny.

no plastic taste, easy draw, perfect size.

The CamelBak Omega HydroTanium Hydration Reservoir is great - just what you would expect from Camelbak: simple, durable and most importantly, it won't make your water taste like plastic! Highly recommended.

Easy to fill, easy to use! This new version of their classic reservoir is puncture resistant, has an anti-microbial agent in the resin, and the cap is even easier to open and close. Don't settle for a substitute, go with an original- Camelbak!

Bought this bladder to replace one that was not BPA-free. It is a perfect mtch to the one inside my CamelBak. I use this when I ride my motorcycle to keep hydrated in south Louisiana heat and wouldn't think of being without it! Perfect amount to consume between stops.

I wouldn't take this into space, but it does the job, is a brand name and is worth what I paid for it. If you've got complaints about it, then you might have the wrong expectations because this is a $25 bladder. Don't expect it to perform like a $125 bladder. This is essentially a quality 2 liter bottle with a cap and a 3ft. straw.

The CamelBak Omega HydroTanium Hydration Reservoir is very high quality. It is easier to close that the previous generation with an obvious stopping point when closing and I haven't had any issues with leaking.

perfect for all my packs. I recommend the 100 oz, its a good weight and be filled as full as you need.

As many others have stated this is a great piece. Go big and use what you need, when you need it. You will not regret it. Much better taste and ease of use than past models.
