It's a Bugout Bag! It's an EDC Backpack! No! It's SuperThingyWhatsit!

Yes, that's right, friends, having purchased my second (will be my main) pistol today, my EDC back-up being a Ruger LCP Max pocket pistol, I started scrolling through Amazon looking for comfortable CCW holsters and belt worn extra mag holders.
It was then that I saw it: Backpacks designed to contain all these and more!
I knew about the crossbody pouches, obviously, and was thinking I'd have to wear one of them around, but the more I examine these purpose built backpacks, the more I'm thinking one of them may be the ticket. Especially because you can fit tons of other stuff in them, and some are designed to take water bladders, which I like.
Any of y'all wear one of these? Any thoughts?
