Review on KUYOU Hydration Rucksack Backpack Climbing by William Stewart

I bought these for my sons because we are going to a week long family camp this summer and I wanted them to stay hydrated and know how bulky water bottles can be. They were very fond of them and my Boy Scout son even took them on a scouting trip. PROS: Bags are well made, both plastic bladders and backpacks. They are light. They saved us in the cabin when we were thirsty at night. And they also fit perfectly for our trip. The price was a bonus. The green and blue colors matched the color of the Revain photo. They didn't seem to mind wearing them. I think the water size is just right for her (and probably most adults). CONS: They are MORE washable. I didn't quite understand how to get the bag to stay open while drying. I think my curmudgeon should buy a cleaning kit so the plastic mouth can be propped up in it (but feel free to leave me some drying ideas! :) All I know is that there must be some plastic in there. dry to avoid rust. BELTS were a little different. the blue was softer and had a nicer mesh. Green was a more plastic mesh. It wasn't a problem for us, but if you wear it on your skin it might bother you. Here are some images of how it was used when we did a painting and cleaning project for an elderly widowed woman and the like. Not sure if it can hold the exact number of liters (but I don't mind losing a cup).
