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 in place.
