Dual Hydration Bladder 2 Liter,Water Bladder for Hiking Backpack Leak Proof,Water Reservoir for Hydration Pack,BPA Free,Carry Water and Electrolytes,TPU Material

Normally I run with two 550ml soft flasks in my front pockets of my vest, one with liquid nutrition and the other with water and electrolyte tab in it, but I’m running a 50 miler with aid stations that are far between each other and I’m so paranoid of running low on hydration. This works great at being able to have water with electrolytes In one tube and my nutrition in the other but 2 liters of each rather than just the 550 ml’s. I didn’t use the whole 2 liters, I’ve been doing 1.5 of each and it’s working great. I’m not a fan of carrying hydration on my back, but I’m a bigger not fan of running out of water or nutrition and bonking because of it. No leaks, easy to fill and clean. I’m 5’0” and I don’t look like a ninja turtle while carrying it.

I have historically either carried two bottles or a hydration pack and a hydroflask in a pocket on my vest. I always like to have plain water when I run, but having electrolyte drinks for the long runs is important.This bladder is well made and I really like the connectors used to connect the tubes to the bladder: they're secure but easy to connect and disconnect. It comes with quite long tubes, which is nice so that you can trim them to meet your needs.My main complaint is that it is challenging to fill both sides of the bladder since the mechanism to seal the bladder uses the same component for both "halves." This means that you have to fill one side and then hold the bladder while you fill the second side so that it does not spill. A little planning ahead is helpful and I suggest filling the non-water side first so that you're not having to try and hold the bladder half-full of water while trying to mix electrolyte for the other side. Also, fill both sides with ice at the same time to save yourself the hassle! Note that I didn't take a star away for this since it is just something to be aware of and a bit of process planning can work around it.Another minor nit, because I have become accustomed to other bladders that have the closing mechanism "attached" to the bladder somehow, is that the piece that is used to seal the bladder is not attached to anything. It is just a minor complaint, but something I noticed when I was filling the bladder.It is nice that they include cleaning tools. Along those lines, the water I drank from the bladder did not have any "weird" tastes.Overall, it is a cool idea and very nice bladder that is made of quality components and I am happy with it.

I am very happy with this bladder I have only used it a few times so far and it is working quite well. It does have a plastic tast as many new hydration bladders do so you will want to condition it for a few days with a vinager and baking soda or lemon soaks to get rid of the taste before a long run. The seams are actually welded with a waffle pattern making it feel like it will be durable and leakproof, not sure what the other reviewer was doing to make it leak unless theirs was defective. I love the 2 reservoir system it work great for separate water and electrolytes. The tubs are long and should fit any vest. The included cleaning brushes are a nice touch. One small nitpickone; one of the bite valves allows a little more flow than the other. Both work perfectly fine I just would prefer them to be symetric.

I really wanted to like this. The idea of two in one. The option of water and some sports drink at the same time. Easy to clean because I can get my hand in there. This is a win. I almost didn’t buy it because some of the reviews talked about a plastic smell or taste. I can only drink bottled water. Tap water has a taste I don’t like. I would never be able to drink water with a plastic taste to it. Another review said they put water in it and squeezed the bag and it exploded. That even worried me. So when it came in. I checked it out. I opened it up. Smelled the outside and inside. Rinsed it out. Put water in both sides, a little over half way. I blew it up with air through the straw. Squeezed and checked for leaks. Made sure it would not pop open. I couldn’t find any problems with it. No smells, no leaks, didn’t pop the top off. I then released the air out of it. Put it in my backpack ran the straws through the holes. I was worried they might not fit, but they did. Drank from both tubes. Took it back out. Poured the rest of the water out. Cleaned the bags. Cleaned the tubes. I feel like it is going to work out great. Only negative thing I can say is this. The cleaning brush with the cable is just a little too short for my liking. I would like to see it about 3 inches longer so the brush comes out the other end of the tube. When I tried to take the valve end off to clean the tubes. The valves came apart. I thought I broke it. Seems like it must have been designed to do that because it just popped back on. There are no instructions for anything. Cleaning, how to put the tubes in, are anything. They did send a nice little thank you card and a email if you have problems. I think this is a good product at a good price. If something goes wrong with it in the first year I will let you know.

I bought these to replace an old bladder. I was a little skeptical at first because of the way it closes. I'm used to the screw on closure. I like the dual bladder idea but if you fill up both sides you may run into some weight issues as it gets heavier with the additional liquid. But I like the idea of having two different type of fluids.Pay attention to how you close it. Mine didn't come with instructions and I put the closure on completely wrong, and when I went to pick it up, all my water spilled onto the floor. There is a specific way to close the bladder using the slide clip so make sure you pay attention to that. Once you get it closed then it's very secure. Now that I've used it correctly, I like this slide closure feature because I can really clean it like I want to. There is a REALLY long flexible cleaning brush for the tube's that I love. It stretches the entire length of the drinking tube, so I'm confident that I'm getting it clean.

Water Leaking from the joint of the hydration pack . My backpack was totally wet in the cold 10 degree and I was with no water on a long hike. You can not trust this hydration pack for your hikes.
