We bought the green for our newborn grandson because his parents love to go go go on the weekends. This is perfect to hold all of his little boy needs while the diaper bag can just those necessities!. Got the idea from our one year old granddaughter that has one and her active parents use it all the time. I'm sure it's great for big people, too. I looked at a lot of these traveling backpacks and chose this one with no regrets.
