>> Applesac 13" MacBook Sleeve by Colcasac Review
I received a new laptop sleeve from Colcasac called the Applesac, designed specifically for my 13" MacBook. This sleeve is very model specific, so when I say 13" MacBook I mean 13" MacBook. You'll be hard pressed to get anything else in this thing with such a precise fit. But for those who use said laptop as their machine of choice, read on for info about a pretty slick
product.
