The minimal yet useful design of the Slim Sleeve With Woolenex beautifully protects and complements the slim, streamlined shape of the MacBook, while its durable material ensures product longevity. Incase designed this Slim Sleeve with its refined and durable Woolenex material, woven from 300D and 600D polyester, which maintains a slim shape with the high tensile strength of ballistic nylon, allowing you to use it consistently for long periods of time. The unique weave makes for a lightweight, durable textile with a nice depth of color. Inside, the soft, padded faux fur lining carefully protects the MacBook from bumps and scratches during transport. The Vislon zipper at the opening closes securely to keep the MacBook inside.
