What is about the same size as the Pop Haut but less structured?

I was going to ask( new thread) but since you mention you've looked at the batignolles ( have you seen it in person? ) is it floppy?
I have the piano its very structured, I like the denim because its floppy but i'm wondering if there is a mono bag that is similar?
 
Oh - I just don't know. Now i'm debating about getting the speedy 30 instead. I'm so darn indecisive but I'm really a very casual knock-around kind and the Pop Haut just seems too formal for me?? What to do, what to do....
