Review on 💦 TRIWONDER Hydration Bladder Water Reservoir: BPA-Free for Cycling, Hiking, Camping Backpacks - 1.5-2-3L by Dave Brummet

I like the soft texture of the bag and the quick connection for attaching and detaching the tube from the bag. So far no leaks from this site. I prefer an open pocket to my old screw cap. This type is much easier to clean and fill. I haven't had any issues with the top leaking or the latch moving when using the bag. The only problem I had was figuring out how to open the valve at the drinking end. A few people mentioned pulling on it, but I pulled on the wrong part. As I took the time to examine the valve more closely, I realized that I had to push the two parts of the valve apart to open it at the base, and then bite down on the end to drink. So it has a double latch at the drinking end. There are also no problems with leakage. For those who still don't understand what a drinking end valve is, see the two photos that accompany this review.
