For anyone on the hunt for a smallish, quality bag for a laptop.
I also frequent some photography forums as I do a bit of that too.
And someone posted a link to a Manfrotto BeFree camera/laptop bag that was reduced from £99 to £27.
I had it delivered to work and then had to figure out how to get it home.
As I also had my C-bag at work, I I figured I might be able to take the frame off and use that to get this other one home.
It's almost a perfect fit and, with a bit of fettling, i.e. take the frame apart to slot it through the strap on the back, would be pretty secure. The flap uses clips to close, and as you can see, these also wrapped around the frame.
The handle was bodged in this instance (I used a compression strap to help with tennis elbow), but any self closing velcro (other hook and loop systems are available) strap would work.
