"bought this after my second they are now 2 and 5 and I still use it everyday. fits bottles and water bottles on sides, pockets are very handy. Side zip on large back pocket is perfect to get stuff too deep to dig for. I have had no trouble with any of the zippers and the material has held well. stows nicely under seats during flights, very comfy shoulder straps. Did have netting on one side bottle holder break at seam, but still works fine. I can fit an outfit for each child, wipes, and snacks in the big pocket alone and it does not puff out but keep shape so the bag never seems bulky."
