The sleeve uses magnets for closure and includes a zipper pouch in the closure flap for accessories. It opens flat to create a flat place to work on any surface. It's fit for the latest devices Apple is currently selling. The 100% merino wool felt is naturally durable and padded. It can stand up to being taken in and out of a bag for years with no signs of wear. It's also nice to know that unlike imitation polyester felt, it's biodegradable. 

The zipper pocket/flap is designed to accommodate the charging brick and cable for the laptop.

The 13" Air/Pro size fits all of Apple's 13" laptops including the 2022 Air.
