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

Love the soft texture of the bag and the quick connection that allows you to attach and detach the hose 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.
