The Targus A7 Sleeve Black/Gray is designed to protect 13.3 laptops, Mac Air, Macbook Pro and Ultrabooks from every day wear and tear. The wellpadded interior features the Tri-cell Cushion System which combines additional foam padding with a top-layer of mesh for ventilation. The sleeve is constructed of a durable neoprene material that is water and wear-resistant. The interior of the sleeve provides a protective cushioning for your laptop and has a non-scratch lining. For additional protection, the reversed zipper is water resistant. If used inside of another case, the A7 sleeve provides an additional layer of protection against scuffs and inclement weather.
