Leather selected for the sleeve is full-grain Argentinian cowhide. The tanning process gives the leather its supple feel, deep color, and traditional aroma. Its full-grain structure provides strength and durability. The hides are finished in the USA with surface treatments that further protect the leather. Your device will enjoy the smooth, gentle touch of sleeve's twill-weave, 100%-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.
