First off, this is the first water bladder i've used. It fits well with the backpack i was wearing and held its position quite well, probably because the backpack was tailored in a way that allows an addition of water bladder to be placed inside. It was the Dakine Mission Pro 25L. The handle made it super easy to fill it with water, no spills at all over the multiple times i've used it. It seems durable as well for its size. Bummer mines didn't come with the cleaning brushes or collapsable drying frame, probably because it was a tester product that i received. Don't let that fool you though this is an honest review. The mouth piece was very easy to use, twist a short amount and it completely locks or opens for you to suck on to get water. The tube itself was very easy to remove and clean, even though no brush i used high pressured water and aimed inside the hole. Bladder did its purpose and retained its quality quite well. Doesn't seem cheap at all. Used it over 10 times for multiple days each and it's awesome. Make sure to clean it thoroughly before using, there may be some chemicals in it or something that makes it tastes funky.
