Parent bags

Not ranked on the changing mat. Ranked on whether you can open it, load it, and close it with one hand, because the other one is full. Front access first, then a bag with more than one way in, then side access, then a panel or clamshell last. When you compare finalists, check one thing the catalog can't see yet: whether the bag stands upright when you set it down.

Narrow it down

What matters most?

This weights the ranking toward your pick — bags without it still show up, just ranked lower.
