Laptop sleeves offer good protection for your laptop. In addition, many laptop sleeves are equipped with a soft lining, which protects against bumps. In your search for a new sleeve, make sure to check the inner dimensions of the sleeve, rather than the inch size. If they're slightly larger than the dimensions of your laptop, it will fit perfectly around your laptop. If you find it annoying that you can't easily carry your laptop sleeve, you can of course also buy a laptop backpack to put the sleeve in.
