WACOOL3L 3Liter 100oz BPA Free EVA Hydration Pack Bladder, Leak-Proof Water Reservoir

Doesn't leak, Easy to dry!great quality.

I used this bladder for an Appalachian Trail section hike in the summer of 2016. It fit perfectly into the hydration compartment of my Kelty Coyote 80 backpack. I had no "plastic" taste, no leaks, and no malfunctions. I was concerned that the hose might disconnect or otherwise leak in my pack (and I was pretty rough with it at times), but it worked like a champ. I was able to remove it and reinsert it without emptying my pack -- I just pushed it (forced it) into the hydration sleeve (like I said, I was pretty rough with it at times).The clip-closure on the top is a MUST HAVE. It's way easier to fill (and clean & dry) with that wide opening. If you are hiking in an area with trickling water sources (or just a shallow puddle fed by a trickle), this thing is easy to fill by just opening the top flap.I cut my tube and inserted a Sawyer Mini filter "in line". My buddy was filtering water into hydration bottles. He wasted a lot of time filtering a each water stop, and it was much harder for him to "drink on the go". This one also has an insulation sleeve, though I'm not sure it did a lot to help keep my water cool(er).The only issue I encountered was with the push-on / push-off "shutoff" on the bite valve. If I pulled too hard to open the safety value, the end would pull off entirely. It easily snapped back on, so it wasn't a big deal for me. I just learned to be a little more careful opening the shutoff (or just leave it open since very little water drips from the bite value when you aren't biting down on it).This was a great product at a great price.

Somehow in a recent move I had lost the original bladder that came with my Ascend pack. This bladder is a great fit! I like that it has the top fill option, as well as the side fill. I read some reviews that mentioned that the top fill closure doesn’t seal completely, but I’m used to this type of closure and haven’t had any issues with leaking yet.I also read some reviews about the bite valve being hard to use. I guess I’m used to picky bite valves, as I’ve not had an issue with it either. You do have to make sure that it is pulled out in the “open” position to use it.Overall, great product for the price! I’ll probably be ordering another as a backup!

Pros:* Large 3 liter capacity* Convenient fold-top for easy cleaning and drying* Appropriate hose length. Not too long or too short* Compatible with most bags designed for backpacking* Cheaper than name-brand bladdersCons:* Neoprene hose insulation does not keep the water in the hose cold* Hose insulation is held on weakly with heat-shrink tubing and comes loose easily* In under a year, the female side of the quick-disconnect started leaking. It only leaks when the bag is completely full and hung upright, which you'll only catch once the bladder is in your bag. I was able to repair this leak by lubricating the gasket and both sides of the quick-disconnect with keg lube, a food grade lubricant for connecting liquid lines. You have to get the lube on a q-tip and press it past the white ring you see on the female side. Remove the gasket on the male side and made sure that side of the connection is lightly coated as well.

I got two of these (green and blue) for my wife and I to have on a 3 day backpacking trip. They were awesome.Pros:-No leaks. I intentionally took the top opening of severally times to see if I could get any drips out of it because that had a been a complaint I read about. I had no such issue, even when it was full and held upside down.-Detachable hose. This made it easier to fill and I was able to keep it clean/out of the way.-Cover on the hose. Wow, when I first opened it I thought it was shooting as heck, but oh man was I glad it was the! (I'm apparently more clumsy than I thought).-3 liter bladder. How a lot of water, though I had to go over the screw on lid to get 3 liters of water in there. Not a con because it is still a lot of water for a cheap price.Cons:-Annoying to clean. This doesn’t warrant a star off because I’ve never had an easy to clean bladder. But the insulated(?) padding’s around the hose makes it stay damp and gets dusty/dirty. Minor nuisance.Overall, Depending on durability,I’d Purchase these again and again.

taste was perhaps a little off but overall it's durable, it works well in my hiking rucksack. flow is a bit of a workout at first. good size.

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 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!

Nice sleeve on the tube, easy top sliding access to drain and fill the bladder and the plastics are quite durable.

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.

I brought this bladder for a 3 days backcountry trip because I wanted more than the 2 liters I already have. It does the job, the only downside is that the cap on top of the bag is a little big and takes some extra space in the bag. Otherwise it’s fine and I like the fact that the tube is insulated.
