I really needed a carry on bag for camping and trips. I've bought bags in the past that were big and bulky. They were very difficult to store and we are not fat like this one. So they seemed to tear easily. I like the design very much. This brings me back to my nursing school days. It is very sweet. The little one is perfect for medication and lotions against burns and insects. I have a feeling it is an estimate. It's not too high a price for what you get.
