I purchased the updated 13 inch rMBP recently for the upcoming fall semester and I purchased the Amazon Basics sleeve to go along with it but it isn't quite what I'm looking for. I already have case logic backpack so the sleeve is just to add extra padding while it is in the designated laptop compartment in my bag. The Amazon Basics sleeve opens from the long end and has a zipper. I'm looking for something that you put in from the short end and has no zipper. That way I can leave the sleeve in my bag when I pull out and put back in the macbook. I've looked around on amazon and ebay but can't quite find anything like this though I've seen it around before. If anyone can point me in the right direction I would really appreciate it, thanks!
