Any Ideas for Travel Bag/Case for Surface Pro + Headphones + ...

Camera + Phone + Odd sized travel accessories such as a shave kit + etc.

I am thinking of carry on plane travel for long haul trips.

Any ideas?

Background:

I use the Tocano Work Out Slim. It's almost perfect. Extra room for the phone lengthwise as it was designed for a 13" laptop, so my phone fits above my surface pro.

But it's to THIN for my headphones and my almost small camera + extras such as the sandwich I bought in the terminal. (And I need that sandwich!)
