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

This hydrapak is amazing -- I'm a rock climber, and I've put this thing through the ringer. I attach it to my harness by putting a carabiner through the sturdy built-in loop (along with all my other sharp gear, but it doesn't pop), and it's great because it doesn't leak at all and it gets lighter/more collapsable the more you drink from it. Perfect for my adventures. I've taken it on climbing trips to Mexico and the Black Hills with this thing hanging on my harness on multipitches and chimney climbs where I'm literally squishing it with all my body weight against sharp rock totally expecting it to pop, but it survived! And it doesn't negatively impact my climbing. On my most recent trip it finally popped a teeny hole at the top; it's still usable but sounds funny because you're slurping in mostly air to get to the water, but I intend to patch it and expect it to be completely fine. But for $19, I'm so impressed that it didn't pop sooner, and the price makes my decision easy to buy a spare.Some people in other reviews complained about the water tasting funny in it -- I never noticed any issues with that. Granted, sometimes when you're adventuring you don't have access to water that tastes to one's liking anyway, and I'm not super sensitive to that as long as it doesn't taste awful. As the sun hits the hydrapak, the water starts to get warm and maybe adopt a slightly "off/stale" taste, but it didn't bother me at all. I am super impressed with this collapsable water bottle!
