Using strengthening methods in conjunction with modern finishing processes, the sleeve's exterior is a waxed-and-dyed cotton, that is durable, flexible, and beautiful. The material is both water-resistant and color-fast, offering your device and larger bags reliable protection on every side. Your device will enjoy the smooth, gentle touch of the sleeve's twill-weave, cotton lining. Backed with a protective cushion of cross-linked foam, the sleeve's snug fit will also shield your device from any accidental drops, bumps, or spills.
