My 13-inch MacBook used to swim around in padded cases that were thicker than a paperback novel. These fit like a second skin and slide right into a messenger bag or tote without fighting for space.
















Bigger laptops are where bulk really becomes a problem. I almost gave up and just started carrying my 15-inch naked until I found sleeves that actually respect the laws of physics.















Carrying my charger loose in my bag meant tangled cables scratching my laptop. These sleeves have just enough pocket space for a charger without turning into a whole second bag.















Regular sleeves slide in horizontally, which only works if your bag is wide. I switched to vertical designs after realizing my tote was too narrow for anything else.
