Our original diaper backpack was way too bulky -- this is smaller, but spacious enough to fit what i need, love the side pockets, and love the look.
Only feature upgrade for the next version i wish for are 2 additional inside side pockets (there are 3 -- one big one on the back, and 2 smaller ones on the front)
Also -- we had to run this through the washer after it got dirty / stained, and it came out perfectly which i did not expect and am grateful for
