WACOOL 3L 3Liter 100oz BPA Free EVA Hydration Pack Bladder, Leak-Proof Water Reservoir

This hydration bladder kicks ass! It's better than the last 3 I've owned, I purchased the 3L. The biggest problem with bladders for me in the past is the nipple, I don't see that'll I'll have issues with this one. This is the best design I've seen to date. I highly recommend it. Thanks wacool!

Great . worked perfect on a remote location photography hike shoot in the bottom of the Grand Canyon 9 miles down

I've been able to use this on a few trips (5 short hike/camp trips) now and really like this bladder. I've had this less than a year and will update if the life of this product changes. Having the top piece that is easy enough to put on and take off to clean the bladder is great and it doesn't leak. I really like the mouthpiece set up. The straw is a perfect length for incorporating into a large pack and attaching in ways that is best for your personal preference. The mouthpiece is a "pull and bite" -- so you pull to open the straw (like popping up the mouthpiece of a water bottle) and then bite down to open the flow. Water flows easily considering the length of the straw. If you use it how the instructions indicate (which is the same as most other bladders) there shouldn't be any problems (e.g keep from sun rot, clean with gentle products, use for water only, clean and dry immediately after use).

I am upgrading my initial review from 1 to 4 stars. Here is why:1) Initially, I gave this hydration bladder only 1 star because it failed at the basic purpose of the product's intended use; namely, to keep water in. Mine leaked right out of the filler cap area the first time I put water in it, and I was obviously disappointed. If it leaked, none of the other features like the locking hose or the mouthpiece cap really mattered.2) WACOOL customer service reached out to me because I was looking for a way to return it and not only sent me a new one, but also offered to refund my money. That right there is EXCELLENT customer service, I give it another star simply based on the support and standing behind their gear 100%. Even if I decided I didn't like the bladder for some reason, it cost me nothing to give it a second try, so 2nd star I automatically awarded for WACOOL's great customer service.3) The 3rd star...WACOOL sent me a new replacement and I tested it out...it also leaked, though not quite as bad as the first one. [Note: I was not testing these bladders to capacity either at this point, nor was I putting significant pressure on the bladder itself, such as might be experienced when in a camelback or backpack.] I played around with different amounts of water in the bladder, and the closer I got to "capacity", the more it was prone to leak a little around the cap. Again, not quite as noticeable as the first one, but enough to be annoying and knowing my gear would get wet eventually. HERE IS WHERE I FOUND THE SOLUTION!! As I had just spent half an hour making a mess on the counter again and was about to give up, I made one more attempt: I took the cap off one of my old Nalgene bottles and tried it on the hydration bladder. Result: NO MORE LEAKING!!! At this point, my Nalgene is now without a lid, but since the point of me buying a hydration pack to begin with was to increase my carrying capacity and move away from a hard plastic container in my pack...this is a sacrifice I think I am willing to make. At this point, the other features like the locking-hose, mouthpiece cap, you can remove the hose even while bladder is full, the slide open/close access at the top actually began to matter now that the hydration bladder was not leaking on it's own...these all earned the product a 3rd star.4) The 4th star is awarded because once I found that a Nalgene lid fit and solved the leak issue, I filled it all the way to capacity and began to give it a real-life test with a little bit of pressure...ok, I was probably border-line abusing the hydration bladder at this point trying to see how much pressure it would take to fail...and it didn't. Not only that, but I never had an issue with any leaking at all out the slide open/close fold at the top, which is pretty impressive right there. Again, I put it through the ringer this time...and I was gaining confidence in the bladder material and seams and was impressed with how much pressure it was taking...I don't know exactly how many pounds of pressure I put on it, but it was at least 10-15 on the conservative side, and that was with the bladder maxed to capacity.**) I did not give it the 5th star for the following reasons: I had to sacrifice a Nalgene bottle to get a lid that didn't leak. Also, the measurement markings on the bladder are slightly off, and it doesn't truly hold 3L in the bladder: I measured exactly 3L in 1L increments and couldn't get 3L to fit without having to dump some out to close the bladder.OVERALL: It's a good hydration bladder. I'm happy with it now that I swapped the lid, and WACOOL's customer support was great. I'll probably buy another WACOOL bladder simply because their service was great.

I thought mine was a good deal: A water bladder with a cleaning kit for $23. It may not be the best in the world, but if you're looking for something that works and don't mind if you lost it either, this is a good choice. Mine didn't leak at all and the hose worked.-The bladder material is made of lightweight but tough rubber. I don't think it'd puncture that easily.-The inside has a very smooth, glass-like feel. I think it'd clean easily.-Their customer service is AMAZING. Great people.Note:-There is a plastic ring where the hose and the mouthpiece meet that slides up and down to lock/unlock water flow. It's a bit stubborn at first, but move it a few times and it loosens up. It's not broken. And you have to bite the nozzle to get water flow.-Be aware that the top is open and folded over, and secured by a plastic clip. ***Be sure to slide the white core piece of the clip IN BETWEEN the fold, or it'll slip off and water will be everywhere (you'll see when you get it and find out why I say this). It's good that the top is open for extremely easy cleaning (better than trying to brush through the fill cap), but it is another opening and that may be an issue for some people. But so far, it doesn't leak around the fold and the clip holds the entire weight w/o slipping off.I had doubts about the open top design, but it works. If anything, it has the benefit of being able to stick your whole hand in it for complete cleaning. I'm actually thinking about getting another one as a spare.

I received this water bag in time. I am starting to use when I do hiking now. It looks very cool. its quality is pretty good. I strongly recommend this item to others who is looking for similar product. The price is very reasonable. Thanks a lot! And I may buy more product from you in the future. Good product from a nice seller.
