Laptop sleeve are nice, I used to use them... but they need to be the _perfect_ size for your laptop.

Otherwise they are hard to open/close if they are just a bit too small, or they are floppy if they are too big.

I currently have three laptops, they all have their own dimensions. So I would need three sleeves to carry anyone of them at any given time. For work, I switched between three sizes in the last two years.

Meanwhile, my 5yo hiking backpack with a water pouch dedicated space is able to carry any of those laptops safely.
