it fits me and the kids both like it

we have two kids and one on the way. That is one more than our Phil & Ted stroller will carry. I tried on the Phil & Ted pack with the stirrups but it seemed too bulky and the center of gravity was too high. This deuter is lightweight, adjustable to fit the 9-month old and the 2.5-year old with little difficulty. Their weight is higher than a normal backpack but not so much that I feel as I will tip over even if I have to tie my shoe. Also, the straps for me are easy to adjust so my wife can wear it if she wants to. Under the kid's bottom is ample room for a diaper, some wipes, and a few other things.
