Just arrived so haven't used. Looks really good...But there is no inner small (secure) compartment at all unfortunately. To help organise the many things I usually carry in such bags. And especially to keep money or keys safe inside.
I've been using these kind of bags for years, and they all have at least one zippered inner pocket. Bought this in a hurry and didn't realise it was so 'basic' in that respect. I hope the makers may consider adding at least one inner pocket to a future design.
