Review on Ultralight And Packable Water Bottle - Hydrapak Stow - Collapsible Squeeze Bag Pouch For Travel by Alan Sitton

After a few uses a pinhole leak started right where the reinforced neck piece comes in contact with the more flexible body material on top of the water bottle. It appears either to be a wear point from the bottle being rolled up and secured for storage or during the reinforcing of the plastic ring there during production a rough spot formed and caused wear. Either way it lasted less than about 4 uses before leaking. Like the concept but need a more durable product I can trust for long treks vice a leaking water bottle after a few uses.
