Sleeve is designed to keep MacBooks safe while remaining portable.

Today, Incase announced the new Slip Sleeve with PerformaKnit for the 13” MacBook Pro and MacBook Air, and the 15”/16” MacBook Pro. The innovative slipcase features a lightweight fabric in a minimalist silhouette, designed to keep your MacBook safe and secure while remaining portable.

The Incase Slip Sleeve with PerformaKnit was designed by leveraging a computer-generated custom stitch-knit that forms a strong, protective barrier for the MacBook without the extra bulk seen from conventional sleeves. The elastic-like qualities of the PerformaKnit fiber allow the sleeve to conform to the shape of the MacBook, hugging and safeguarding every curve, contour and corner so it remains free of scratches, nicks and dings while on-the-go. 

The Incase Slip Sleeve with PerformaKnit is available now for the 13-inch MacBook Pro and the 13-inch MacBook Air with Retina Display, and the 15 and 16-inch MacBook Pro. It is available in burst, graphite, and asphalt for MSRP of $59.95.


  • PerformaKnit’s robust fibers are designed to stretch, permitting the sleeve to seamlessly adapt to the shape of the MacBook while eliminating excess bulk. 
  • The strong weave makes it ideal for keeping the surface of a MacBook free of scratches, scrapes, nicks, and dings.
  • Easy-handling streamlined shape looks great anywhere – home, office, school, and on the go. 
  • Magnetic snap enclosure keeps the PerformaKnit slip sleeve securely closed and a user’s MacBook safely inside.
