Over the past year I too have been collecting top zip bags (with outside pocket/s) for quick access. I travel and have found the square bags pictured above to be my go to options because they have good depth which easily accommodates the usual items I carry with me. Each easily fit into my Musette or Carrier along with other stuff when I need a larger briefcase or carryon too. I have found center dividers don't fit everything for me and are heavier. I do have one Sonoma Sheridan Mayfield divided bag I use for running errands daily that I love but don't carry much in it.
My ziptop bags above showing size variation....I don't find any of them heavy when empty.
#9706 Skinny Flight Bag 12.5x9x3 - I love this bag (I also have nonstrap black version).
#9855 Classic Hobo 13x10x4.5 - Widest, fits lots but does it say 'old lady' bag? Carries 11x8.5 files though!
#9939 Carson Zip 11x6.75x3.5 - A bit smaller, has two outside pockets and still holds everything. My go to BT bag.
#9399 Companion Bag 11x7x3 - Smallest and lightest, and still works for me.
Smalls shown that I always carry and all fit into the top three bags above!
#4514 Organizer Catty - I actually have two, brown and black! Carries my mini ipad, notepad, business cards and pens. And slips into my bags when I don't need my larger ipad.
#7165 Chunky Case - keeps all my little stuff in one place.
#7170 Skinny Case - I just as my bills/coin purse
#7219 Multi-Function Wallet - Is my card case
The 'Dinky" size Basic Bag black ziptop at the left of the Skinny Flight Bag gets stuffed into all my bags to use as a quick grab and go when a big bag isn't needed or useful.
Hope this helps for some comparisons!
