My MacBook Pro 13er (13.3 with built-in CD drive) fits like a glove into it, and the additional trade fall in disuse and hidden zipper Zipper on hardly offers by the folding system but plenty of storage space for charging cable and Co.
What to write more? It has been successfully used in everyday use, keeping the seams and zippers and there are no flaws in the MBP. I'm very satisfied!
