Review: Works well after I figured out the tube bite valve! - 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. Review: Great price, great value. - Works great! A little awkward to clean but overall not too bad. Love this for my long runs in my vest. ## Features - ✅ SAFETY PROMISE -- Made of food-grade TPU/PEVA material, 100% BPA & PVC free.
