The Slip Sleeve with PerformaKnit, a lightweight textile in a minimal silhouette where protection meets performance. Designed by leveraging a computer-generated custom stitch-knit, PerformaKnit fabric forms a strong, protective barrier between your MacBook and the active performance of your everyday life, but without the bulk you’d expect from conventional sleeves. The elastic-like qualities of each PerformaKnit fiber allow the sleeve to conform snugly to the shape of your MacBook, hugging and safeguarding every curve, contour and corner. Work, school, home or play, the Incase Slip Sleeve with PerformaKnit is the ideal answer for keeping your MacBook safe, secure and on-the-go.
