## Description

Review: A Must-Have For Backpackers - 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.
Review: All around GREAT hydration bladder! - Let me go into this by saying this is my first hydration bladder. They didn't seem practical to use with a filter, and carrying almost a gallon of water seemed to be excessive to me. The price caught my eye, I recently bought a new pack with a convenient bladder pocket, and was going on a lengthy bike ride, so the stars aligned and it seemed like a perfect opportunity to try it out. My first use of this hydration bladder was on a 52 mile bike ride, with 3L of water to start the trip. Here are my findings: -Filling is a breeze. The top has a slide that comes out and allows you to open the bladder fully from the top, and fill it with clean water. If you don't want to go through that hassle, it has a large screw-on lid that you can fill through. Many of the negative review's mentioned this cap leaked, and that was the first thing I tested when I got this. I found NO leaks, even filled to the max. -The hose is one of the best parts of this thing. It attaches to the bladder with a kind of "push in and twist" system, so once its in it doesn't leak, and if you take the hose out to just use the bladder, it doesn't leak either. With the hose being detachable, this also makes it VERY easy to clean. The nozzle on the hose has a dust cover (of course) to protect the actual piece you put in your mouth from any nasty dust/dirt/insects/pterodactyls. The nice part about the dust cover is that you CAN use your teeth to pull it off of the nozzle. This worked great when I needed to keep a hand on my handlebar. -Back to the hose/nozzle, once you take the dust cover off it has a "lock/unlock" system for the nozzle so water doesnt accidentally leak out. You simply pull on the nozzle to "unlock" it, and push back in on it to "lock" it. Basically I would use my teeth to pull the dust cover off, bite the nozzle, pull it to "unlock it", and then suck to get water. I would then bite the nozzle and push towards the hose to "lock" it, use my teeth to put the dust cover back on, and be on my way. This really impressed me, and while I was on my bike for the entire time on a paved trail, the bladder didn't take much abuse. I fully plan on taking this with me on my next long hike, and will update my review based on my experience hiking. So far, this thing is great!

## Features

- Capacity: 3 Liter (100oz), BPA- Free EVA material; Blue x 1 and Green x 1 and Clean Kit x 1
- 4pcs hydration cleaning kit includes 1 x FLEXIBLE tube brush, 1 x BIGGER bladder brush 1 x SMALLER bite valve brush and 1 x COLLAPSIBLE drying hanger rack.
- Might be the most rigid hydration bladder on the market: 0.6mm extra thick liner is pressure-tolerant and wearproof; double soldering sealing side technique has greatly improved durablity.
- Double opening design. As the most popular design for high end hydration systems in recent years, this allows you to refill in any condition.
- To avoid any potential leaking, the screw cap should be securely closed as tight as possible! Twist the lid clockwise to fasten it tightly until the lid can not move any further under force! Please do not hesitate to mail us first if there is any issue about the product.

## Questions & Answers

**Q: Does it come with water?**
A: What type of water does it come with?

**Q: How to clean the hose?**
A: Cleaning the hose is different from cleaning the bladder. You can clean the hose with a long handled, narrow bottle brush. The hose unclips from the bladder which means you can directly clean as much of the hose as your bottle brush will reach. There are several suitable bottle brushes available on Amazon. Searching for "Munchkin bottle brush" will return some good options.

**Q: What proof is there that this is pba free and will it fit in my walmart ozark trail outdoor equipment backpack?**
A: the test report release by SGS, Report No. is GZHG1411043611SP.and we don't know if WACOOL 3L bladder will fit in your backpack,you can measure the backpack`s interior space and then compare it with our bladder's flat size.

**Q: What's the trick to make this thing stop leaking? Carried it hanging in my ruck, and the bar separated from the bag. Screw top also leaks...**
A: Make sure you slide  the bar tightly against the bladder's  plastic  top, doubled over. Don't touch the bar while hiking. I don't know why the screw top leaks. Make sure you tighten it securely. .

### ⭐⭐⭐⭐⭐ Good bladder for very good price
*by J***K on July 20, 2018*

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.
