I received this water bag in time. I am starting to use when I do hiking now. It looks very cool. its quality is pretty good. Having the top piece that is easy enough to put on and take off to clean the bladder is great and it doesn't leak. I really like the mouthpiece set up. The straw is a perfect length for incorporating into a large pack and attaching in ways that is best for your personal preference. The mouth piece works good but thinking I might remove the cap because it gets in the way and I don't really use it. Very well designed and sturdy water bag, with plenty of available carrying capacity. I will be buying more for friends!
