Im looking for a good quality zippered hardsleeve, looking around its tought theres dozens but does anyone know of anything like a sleeve with memory foam on the inside that zippers more than just one side and is firm all around so it can take a small fall? sort of thin as well nothing to obtruse would be amazing!!! its just got to survive in my messenger bag for classes here in San Antonio any insight would be amazing! One that ive been looking at was the hardcandy bubble cases, anyone have any experience with these or anything? are they worth while or garbage?
