Why we cut this one

This is our shoulder bags and briefcases made for MacBook Air 2025. The A3114 pattern is ours. the handle and the strap are already on it, so the fit is a fit and not an approximation.

The strap anchors are riveted through a doubled panel, because that is the seam that tears when a bag is full. That matters more on the MacBook Air than on most machines, because its lid is the widest flat panel you own and the first thing a dropped bag finds.

Pack the MacBook Air, then a slim charger, a cable roll and a key pouch, and the black shell still closes flat — the pocket was sized after the machine, not before it.

The Black finish is what this listing is in 15.3 inch — it was measured against 15.3 inch Macbook Air M4 2025/M3 2024/M2 A3114,16 inch Macbook Pro M4 2024/M3/M2 2023 A2991 A2780 A2485(A485S).

Before you buy

Does the A3114 hold its shape with nothing inside?

It does. That is the point of moulded EVA — the case stands on a shelf empty and does not collapse into a fold, so the MacBook Air slides back in without a fight.

Does it fit in a tote as well?

Yes — the outer walls of the A3114 stay flat, so with the MacBook Air inside it drops into a laptop compartment or a tote without bulging.

What if the MacBook Air turns out to be a different revision?

Fit is the one thing we would rather you check twice. Compare the model number on the base of the MacBook Air with the list on this page, and if it is not there, send the case back through the order page of the store you bought it from.
