Compatible sleeve for 13 inch MacBooks

The MOSISO A3404 sleeve fits MacBook Neo 13 inch 2026 model A3404, MacBook Air 13.6 inch M5 M4 M3 M2 2026-2022 and MacBook Air 13.3 inch M1 2021-2018. It also covers MacBook Pro 13 inch M2 M1 2026-2016. Internal dimensions are 12.6 x 0.79 x 9.06 inches.

Protection limits of soft PVC construction

The case uses polyvinyl chloride with 360 degree polyester foam padding and fleece lining. It guards against bumps, shocks and scratches but is not rigid or waterproof. The top-loading zipper provides access while the soft shell adds minimal bulk inside a larger bag.

Upgrade from basic slip cases

This sleeve replaces thin neoprene or felt slips that lack padding and accessory storage. The detachable pouch measures 5.11 x 0.59 x 4.72 inches internally for mouse and earphones. The jump is worth it when you want shock absorption plus a matching small pouch in one coordinated set.
