WOW....thank you for all of those ideas!!!! I will check them out. Do any of them have a crossbody strap?? This is a must for me!I am with you with the search for a perfect zipper tote!
Marco Massaccesi makes customizable totes with zippers (midi Selene or full Selene etc) or some models that come with (Modena, Venus, Sienna if you like satchel style).
Von Holzhausen recently released a zipper tote in their Technik Leather - while I am a fan of this brand, I personally found that tote a bit too bulky, but it could have been just me.
Shinola has some new zippered totes and hobos as well.
