Don't waste your money.
This backpack does what it's supposed to do but at a VERY crappy level.  I did not purchase this bag because my insurance covers it for my son, but I would not recommend wasting your money on this. It will drive you nuts!  I'm on my second bag. The zippers broke on the first one; they are very hard to zip back up when the bag is completely opened. I pulled the zipper so hard, one of the teeth popped off so the bag became useless. The strap on the locking clasp inside next to the hook to hang the feeding bag is not stitched to keep the clasp from slipping off; again useless.  On my second bag, the stitching on plastic window for the pouch of the pump came loose now the pump protrudes out.  The stitching that connects the netting that holds the pouch ripped as well, now the pump doesn't sit correctly in the pouch. It's already hard enough when your child is on a feeding pump.  Having to deal with a crappy bag to use so you can take your child out and about should not be a struggle.
