Signature Type Cover is crafted in a stunning two-tone grey mélange style of Alcantara - a unique, proprietary material, sourced only in Italy, with aesthetic, sensory, and technical qualities unlike anything you’ve ever experienced.

Alcantara is a unique and innovative material used in high-end luxury products like fashion, automotive, and interiors. This fabric ages beautifully, growing richer and darker over time, and is wonderfully soft to touch.
