Absolutely awful. These are meant for children. I am 5'2" and while I have a little junk I'm in no way big. I couldn't even get them over my thighs. These also had a run in them. 😑 Annoying

Ex Input:
This is a cheap solution to missing or damaged bite valves on water bladders. Yes, they can leak a little bit. Not really any more than standard bite valves. I've gotten to the point that I buy the cheap bladders and sometimes the bite valves fall off or fail. Generally, the bladders are just as good as the full price ones, sometimes better.

Ex Input:
It's good if you're going to use here and there but for a permanent stay not so good. The tubing is not strong , two of them bent at the joint. And when it rains it collects water on all 6 sides and the center tube come off.
