Review on Moki Kids Hydration Backpack Sparrow by Donald Waller

I bought two of these, one for my 5 year old daughter and one for my 7 year old son. We have used them on numerous hikes and bike rides. They are the perfect size for small children, they are not heavy even when fully filled. Both don't complain about it at all and would love to have their own water. We'd let them hide some snacks in there too. It fits bars, apple sauce, a small bag of chips and some sweets. I usually fill 1/2 serving for my daughter as she doesn't drink everything on short hikes, but a full bag can last 3-4 hours of hiking in 100 degree weather for my son.
