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

Have used these on multiple hikes now with no issues. Very reasonable pricing compared to other brands and good build quality. For cleaning, I usually just rinse it with water, completely open it by removing the plastic clamp and opening the round lid. Then I dry the insides as much as possible using a paper towel, insert a plastic water bottle in from the bigger opening and leave it out to dry for a day or two (see picture). Without inserting something in to separate the inner surfaces, it is very difficult to make the insides dry completely. For the hose, I would just rotate them with all valves open to let the water out as much as possible and then let it air dry. I believe that the cleaning kit that comes with this product (extra $) is not significantly useful. The long cabled brush can be used to clean the insides of the hose, however, I do not find myself using the other items from this kit.

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 must say these performed way better than described! I did the step on them test simply because I could and was pleasantly surprised. Not a leak to be found! I bought two of these, one for my husband and one for myself because we do a lot of hiking/exploring! We are both prior military and wanted something that would hold up as well as a Camelback bladder at a fraction of the cost. All of the bladders we have used in the past leaked, some of them with the very first use! I was a little leery about trusting one more.These bladders have served us well so far and have been through numerous cleanings and refills since we bought them. Still no leaks! The sliding opening was where I thought any leaks would start. As of yet, nothing. Dry as a bone. That is after refilling and drying off the outside. LOL They are easy to clean and easy to dry between uses. If you purchase this bladder, you will not be disappointed!

Product seems to be quite well made, and well-engineered. I was a little worried after reading a previous review reporting leaks at the cap, but thought I'd take the chance, as they also found a fix for the issue. I tested it with water, after doing the suggested salt water rinse. I filled it both partially and very full, and put pressure on it under both conditions. At first, the cap did leak, but after further investigation, I realized I had not tightened the cap fully. There is a beveled edge inside the cap that contacts the filler neck inside the opening, and I only tightened to the first resistance, not fully seating the cap. Once I turned the cap another 1/4 (ish) turn, it was fully seated and leak-free. I have had no issues with either the top seal, nor the quick-disconnect. As far as the insulated sleeve goes, I live in Southern Arizona. Any water you carry, unless it's vacuum insulated, is going to get warm. I had no expectations of magically cold water pouring forth from my water bag, but the sleeve does do a great job of keeping the sun (read ultraviolet light here) from damaging the drinking tube, so I'm happy.

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!

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 put this inside an existing 2L pack and it works well enough. I have been impressed by the construction. The bag is well made and easy to clean.I am concerned about losing the clip as that is the only thing that keeps this bag sealed.Other than that I had to use a small zip-tie where the insulation attaches to the hose because it would slide up and down as I opened the nozzle to drink. Hopefully the insolation cover and proper care will prevent anything from growing in the tube.

This bladder works awesome, no leaks and holds the perfect amount of water for an overnight backpacking trip. The best part is... No plastic taste!!! *Followed the cleaning instructions before use*

Works totally fine! Happy for the outcome from what I spend!The bag fits 2L and it holds the shape. It was a rough walk but the bag survived.Tube is good design, I have no trouble drinking the water and it doesn’t make any mess. You need to bite the tube to be able to suck from it which is great. No water spills, whatsoever.Price is so much cheaper than Anaconda in Australia and with this quality, I’d continue to buy it.

This is a great bladder. I have used it about 5 times now and it works as expected without any leaks. It is really easy to fill because it has a plastic handle around the opening where the water goes in, which keeps the bladder stable while you are filling it up. The bladder also really easy to clean. All you need to do is to unscrew the top and unhook the bladder entirely.I also really enjoy the quick connector of the tube from the bag. It doesn't leak at all and makes it much easier while cleaning the bag or filling up. I will buy more of these when I am back in the market. So glad I got this!

I bought this to run my first 10K, it worked really well for me, I'll keep using it for my next races, it doesn't leak at all and overall the quality is really good.
