Gelindo Hydration Bladder 2.5 Liter 85oz BPA-Free Hydration Reservoir Leak-Proof Large Opening with Insulated Tube Hydration Backpack Replacement for Hiking Camping Cycling Hunting

It's a bit wider at the top than expected, and the hose connector to the reservoir is plastic. I see that being a problem with long term use. It also might be a QC concern as far as tolerance and leaking. That said, mine did not leak. I expect it to do it's job as long as the hose connector holds up. All in all, if all you need is an inexpensive reservoir, this isn't the worst way to go.

I have 4 of these for my daughters and myself. They are very handy and easy to use. Great product

This is my second "bladder" for my hydration backpack. I like that one feels more sturdy than others I have bought (and returned) I like it that is is BPA free and also that it is black, most are light blue. The lid is connected and I like that as well - the tube is free flowing and there is no odd taste.

Good and strong

Great, I like the cover for the water tube, and overall very good. Would buy again.

I used this bladder all winter. Performed flawlessly and was a great value. I’d recommend it to a friend.

Would of been great but right away it leaked so I ended up just tossing it. I should of just asked for a refund:(

Not bad but tittle states quick release tube which it is not
