I have chosen when searching for a cool bag for this pack. I wanted him mainly for when I go to the swimming pool, on the lake or in theme parks with my kids. Therefore, the size was adequate. I find it convenient as it can be taken up on his back. If you similar to parks must constantly carry a bag, it is quite annoying and cumbersome. Here you can store a few drinks and something to eat. For a larger picnic backpack is then possibly a bit too small. You have to just be aware before you buy, what you have for a need. I found it anyway enjoyable than I could him tighten on the back in the park. I can recommend it highly if you need a not so large cool bag!
