Basic Laptop Sleeve:
This is your basic neoprene laptop sleeve that is cheap and gets the job done. The great thing about these is that they are cheap, come in different colors and are light weight so that they do not add much weight to when it is combined with your laptop and in his backpack or whatever he holds his laptop in.
The Advanced Laptop Sleeve
For a more advanced laptop sleeve I would recommended the Thule Gauntlet laptop sleeve, it is extremely sturdy and is sure to last a long time. The MAJOR benefit this has over a basic laptop sleeve is that it is much stronger and durable and will protect a laptop much better.
