I received this bag for Xmas (2017). My heart was set on a Neverfull GM but it was sold out.
The All In is one piece of material, with glazing on the side. It can be folded which I think is unusual but I place it similar to the speedy (which can be folded and is folded at purchase). I believe that is why many may think that it is a bit flimsy.
It can carry a lot. I am about 5 foot and it looks big on me.
I really love the thick straps - reminds me a lot of my Totally.
I definitely think that if you were to put any heavy items to get a bag organiser. Or it might sag like a speedy bag.
I love that it has a zip so I know my items are secure when it is used. Though I don't always zip it up while using it.
It has an internal pocket. Comes with a luggage tag.
The great thing about this bag is that you are able to adjust the width of it with the size of a bag organiser. I own 2.
When I used it and carried a laptop, few ipads, a cardigan, purse, phone, keys. It wasn't filled up but I stopped there because it was too heavy for me to carry.
I sometimes use it as an everyday bag. And always with an organiser (for shape).
