Two design changes would turn this backpack into perfection
"I LOVE this backpack with all the pockets, the space for shoes (or a bento box for packing lunch), and the connecting/detachable cross-body bag. I'm planning to have a tailor remove the keychain connector from the front lower pocket and sew it into the crossbody, which is where I will keep my keys. The other change that I would love to see is the addition of a zip pocket to fit a phone located on the exterior backside of the crossbody (so it would be against the body)."
