This is a really good bag. The quality is great and it has quite a few pockets to keep things organized.
It fits my MacBook and iPad easily and Im sure it would fit a MacBook Pro 13 very well.
I took off one star as I believe the shoulder strap is a little too thin. On my first trip using the bag as a carry-on, I was constantly having to pull the strap up on my shoulder as it would slide down.
