Review on KUYOU Hydration Rucksack Backpack Climbing by Josh Cooper

Very comfortable for cycling, hiking or very long runs. I took my kids to the local parade on my bike and took two kids in a bike trailer. It was hot and I knew I needed some water but I had nowhere to store it on the bike. After our return I was looking for this type of product to be better prepared. That's cool! It's like a water bag. It's easy to use and has extra compartments for storing keys, sunscreen, etc. I like the large water bladder opening because it's easy to fill and clean. I tried it on a short run and a short bike ride and it worked great. I will only say that the color is not as bright as in the picture, but in any case I like green. We are ready for our next long bike ride!
