The Targus A7 Sleeve with Ariaprene is designed to protect a 12" netbook from every day wear and tear. The well-padded 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 Ariaprene, a durable material that allows for zero waste as production scraps are recovered and used to make Ariaprene pots for plants and padded playground flooring. And unlike comparable materials, Ariaprene will degrade overtime in a landfill to help reduce waste. A7 sleeves made with Ariaprene provide protective cushioning for your netbook in a durable, water-resistant cover. If used inside of another case, the A7 sleeve provides an additional layer of protection against scuffs and inclement weather.
