I am thinking about buying Proporta Sleeve for my MBA 13 inch. But, this was designed for Macbook/Macbook pro 13 inch. Macbook pro and Macbook fits in very tightly. I have not been able to find any video or anything about proporta sleeve with MBA. Does anyone use proporta sleeve here with their 13 inch MBA? Could you please provide me some feedback? Will it be too big for MBA? MBA is so thin compare to MBP, so I am worried that it might just bounce around too much inside the sleeve. Thanks in advance.
