This product is really great.  I originally bought it because i needed a laptop sleeve. I was tired of lugging around my big laptop bag and wanted to be able to put my computer in my backpack without damaging it. The colca sac does a good job of that. it has a soft fleece interior lining that prevents your computer from getting scratched, and has a handy pocket on the outside for keeping your power adapter. Only thing I would change is the velcro.....it can be sort of loud when you’re in the library!
