Review: Perfect backpacking water bottle - A new must have for my backpacking gear. I use a CamelBak for my water but wanted something I could add electrolytes to and this is perfect. I don't go fully ultralight, but pretty light weight. This collapsible flask is perfect for a light weight water bottle that compacts down to almost nothing when it's empty. I've had it on 2 easy backpacking trips already totalling 10 nights. 2 more trips coming up to finish off the summer. Does not leak. No bad taste even the first time using it. So far it seems very durable and I'm sure I'll replace it if it ever wears out. Highly recommend. Review: Love the twist to lock - These are great flasks that twist and lock when needed. I usually store one in the back of my running vest, and I can be confident that it won’t leak bc of the locking system. I prefer these over bladders. I’ve had a set of these that I’ve used for years, and just bought these extra ones a longer event. ## Features - Collapsible soft flask running water bottles are designed for runners.
