Fits perfectly on my small 13" MacBook Air. If you wish it can also fit in your briefcase. This makes for neat packaging that protects the laptop very well. It has a good thick padding. Neatly sewn, the material does not fray. I also like the sturdy handles and shoulder strap. Finally, I like the combination of black with orange (brown) that I bought better than I expected. The color is rich and doesn't wash out.
