TRIWONDER Hydration Bladder Water Reservoir 1.5 Liter 2L 3L BPA Free Water Bladder for Running Cycling Hiking Camping Backpack

Great bladder. It's made of high quality material, very easy to clean. No aftertaste in the water. It's also very easy to clean.I have only used it once but very happy with it. Make sure you dry it completely after using it.

I like the soft texture of the bag, and the quick connect to attach and unattach the tube from the bag. So far, no leaks at that end. I prefer the slide open top type bag to my old screw on and off top. This type is much easier to clean and fill. I have had no problems with leaking at the top or the slide moving when I am using the bag.The only problem I encountered was figuring out how to get the valve at the drinking end to open. Several people have mentioned pulling on it, but I was pulling on the wrong part. Once I took the time to look at the valve more carefully I figured out that I needed to slide two parts of the valve apart to open it at the base, and then bite down at the end to drink. So it has a double lock on the drinking end. No problem with leaks here either.For anyone else confused about the drinking end valve, please look at the two photos included with this review.

Use it for running, with one of their hydration vests. This is a good inexpensive product, i think. I used it on a 16 mile run and I can't tell if it is leaking or my back is sweating. It maybe my back and if that is the case i don't like the feeling of my sweat against the cold bladder/ This would be a me problem and not a bladder problem. Also 2L is apparently more than i need for a 16 mile run . This will take a learning, so no penalties on them all on me. One suggestion clean out and air out this unit for a while before first use.

This water pouch worked well. The opening is large, and it’s easy to fill it with ice and water. The only real problem I had with it was that you get very little water out of the bite nozzle. I ended up ordering different bite nozzles. Highly suggest ordering new nozzles more like the Camelbak ones.

The item appears like maybe it was used and returned. It seems like there was moisture in the hose before. I missed the return window. I'm not comfortable using it if it may have been used before due to risk of germs, mold, etc. so I will be throwing it out. I can't comment on how well it works since I haven't used it, but I was expecting a brand new, never used product. I ended up buying a different one.

I contacted the company to see if I was able to get more o-Rings for the hose attachment to the bag (otherwise it leaks) or if they could tell me the size so I could find more myself (I ordered several o-rings from another vendor, but there were the wrong size.) The company’s customer service was basically non-existent. That said, I love the bag, the hose attachment type, and the bite valve so I ordered another setup. This time the hose and bag came with 2 extra o-rings. Now I have an o-ring for my old set as well!

Sturdy, holds a good amount, hose is super long and hard to finale with, and also big curb for learning to use the straw, it's weirdly difficult to get it situationed to get water flowing. Have used the camel brand before and the mouth piece was better with the lock down on that

I ordered this bladder to accompany my Triwonder 5.5L running pack: https://www.amazon.com/dp/B01DO2TDVWThe bladder is solidly constructed with tight connections on both the o-ring and the drinking end. The length of the drinking tube is adequately long and can be easily tucked down in the front of the pack or cut to size if needed.The bag has graduation lines to indicate the fill volume of liquid inside.The bag is very easy to open at the top. You slide the plastic piece and unfold and then can easily clean it. Folding and replacing the plastic piece offers a tight seal.I’m overall happy with this purchase and look forward to using it on my long runs.
