After reading all of the rave reviews on this site I ordered two applesacs from the US to be delivered to me in Canada (about $50 dollars canadian each). I just opened them up and I am very disappointed. They look nice but they are VERY thin. The thickness of each side of fleece is hardly enough to properly protect a fragile aluminum macbook (dents easily) inside of a bag filled with books and other items. I am worried about using this as the sole protection for my new 13" mbp.
