We crafted our MacBook Hardshell with premium Bayer Makrolon polycarbonate, a durable material that is remarkably lightweight yet offers MacBook reliable protection from scratches and impacts. And the Hardshell exterior has a Woolenex material overlay – a lasting blend of abrasion-resistant fabric that repels the elements. Woven from both 300D and 600D polyester, Woolenex retains a slim form with the high-tensile strength of ballistic nylon – meaning you can use it consistently over extended lengths of time. The unique weave results with a lightweight, durable textile with beautiful color depth. Additionally, our form-fitting MacBook case features precision cutouts for full access to ports, lights and buttons, and its injection molded construction includes thorough ventilation to avoid overheating and rubberized feet to keep MacBook firmly with place.
