This AmazonBasics sleeve is made of neoprene. It fits snugly around your laptop to cushion it in your backpack. I have this sleeve for my own computer and feel that it is an affordable, all purpose option.
This spill resistant notebook bag sports a watercolor marble pattern that is really unique. If you want something that looks a little different than every other laptop case out there, then this might be the one.
This interesting case from AmazonBasics has a grab handle in the top corner. It seems to be small and compact and the description says it has a top loading zipper, so should be easy to slip in and out of your backpack.
This mandala laptop case is just beautiful. On the outside it is made from splash proof canvas and the inside is a fuzzy gray fabric. I like that it comes with a small pouch for accessories, chargers and cables.
There are so many different choices in laptop sleeves for students.
My suggestion is to prioritize the features that you need and then look for a style that fits your personality.
Remember, its main job is to protect your computer.
One important point – if you don't already have Amazon Prime, it's a good way to get the things you need more quickly.
