Which sleeve do I need for the MacBook Pro 2015?

I recently bought a MacBook Pro (without Retina) from 2015 for cheap money.

Since I have a baby on the way, I want to be on the safe side and get some protection for the keyboard, screen and case.

However, I can't find any suitable items online. Is that because the device is too old? Or have I just not searched thoroughly yet or are models for other devices also compatible with my laptop?

I would be happy about your answers.

So as far as I know there are no cases for laptops would be kind of weird, but there are pockets.
