Hi all, I need to look for my first messenger style bag..and I'm considering between the Tulum GM & Mini Lin Saumur XL. Oh, I forgot to mention that I'm using this bag as a diaper bag..thus the reason why I can't consider the smaller styles. Any opinions would be greatly appreciated. Thank you in advance! (P.s: I don't mind mini lin cotton/linen canvas cos I'm planning to treat it with Vectra Spray; if I were to get it). Cheers.
