What exactly makes these Eastpak x A.P.C. backpacks better than a regular Eastpak backpack? Well, it's got a stitched-on tag that Says "Eastpak" with a smaller A.P.C.'s logo below that, which you clearly don't get with a regular Eastpak backpack last time I checked. It's also got higher quality, vegetable tanned leather accents, which I'm assuming are nicer on this pack than on your typical Eastpak offerings. From a real functional perspective, though, sure, not much is different. Unless of course you counting stunting as a function, which obviously we do.
