I bought an Elberlestock Bandit that seems similar to what you’re looking for, though I haven’t used it much yet.
The H31 Bandit is a great little every-day-carry pack. Its laser-cut MOLLE panel allows you to rack on accessories and provides a place to quickly lash one bulky items outside of the main bag. Open the front-loading zipper and youll be surprised at just how much room there is in such a small...

With 2 and 4 year old boys, I needed something to carry enough water, snacks, and rain jackets for everybody but I didn’t want a large pack as I often end up carrying a kid at some point also.

No hip belt included but you can add one later if you want. Personally, I don’t need to for weight bearing, but would prefer even a piece of 1” nylon webbing the keep the load close to my back. I did like the fact that it comes in navy, grey, etc, as I’m not a fan of “tacticool“ gear for daily use.
It has a horseshoe zip, hydration bladder sleeve, separate upper pouch, and a few little organizer panels inside, two water bottle pockets, and a compression panel on the back. I think it would work pretty well for shed hunting, you could even zip tie them to the laser cut molle so you don’t have to worry about them working loose.
