Hey guys, I'm going to start taking my MacBook Pro to school, but I don't want to throw it in my bookbag with my books because it'll get scratched up. Can anyone recommend a good sleeve? I'm looking for something with no handle or anything to carry it by, just something to slide it into to protect it. My dad just bought a "Just Air" sleeve for his MacBook but it stops at 15.5 inches, and will not fit my 17" MacBook pro. If anyone could recommend anything similar to that, I'd appreciate it! Also, I have a budget of under $40.
