For my MacBook Air the bag is a bit spacious, but I did not expect anything else and so adjusts to even help a notebook in my pocket and my MacBook is sure to fit in well with protective case.
I will use this bag when I try to convey the MacBook ...
One point deduction is available for the still very strong smell of neoprene case. I hope this can be the time for a bit.
All in all a worthwhile purchase ... The design and the workmanship is great!
