Review on WACOOL 3L 3 Liter 100oz BPA-Free EVA Hydration Pack Bladder with Leak-Proof Water Reservoir by Christopher Theriault

This is a good hydration bladder for the money. No leakage. Good water flow from the mouthpiece. Wide opening for filling. The quick connector on the hose will NOT leak even when fully filled with water. It actually rolls up and locks into place. It also comes with a hanger and cleaning supplies. The only thing that really suits me is the black slider on top. You fold the bag and the slider actually squeezes the bag to seal it. It doesn't flow at all. What worries me is that nothing is really keeping him there. There is a small potential that it may partially or fully slip. Either a leak or the loss of all content. I didn't. There is little resistance to the sliding mechanism. I also filled it out and posted it to try it out. Now I haven't beat out the snow or stepped on a bag to rock a 10k mountain climb. But I beat it a little to mimic a daily walk in a backpack as long as it doesn't slip off. At the same time they say YMMV.
