Why we cut this one
We cut this one for MacBook Air M4 2025/M3 2024. Super Corner reinforcement sits in the four corners — it goes into a bag that already has a laptop in it, and it does not change the shape of that bag.
We tried this pattern the way the MacBook Air M4 actually travels — bag on the floor of a train, bag in the boot, bag dropped on a tiled hallway. Super Corner reinforcement sits in the four corners, which is where a dropped bag lands roughly nine times out of ten.
Alongside the MacBook Air M4 there is room for a brick, two cables and a pass. We would rather give you one honest pocket than four that each hold half a thing.
Black in 13.6 inch, and that is the whole difference between this page and its neighbours. It was measured against MacBook Air M4 2025/M3 2024.
