The Targus A7 15.6" Laptop Sleeve is designed to protect 15.6" laptops from scratches and dust. The heavily padded interior features the Tri-cell Cushion System™ which combines additional foam padding with mesh material for ventilation. The exterior features neoprene material with an industry-grade tarpaulin gusset around the edge which is highly durable and water-resistant. If used inside of another laptop case, the A7 slipcase provides an additional layer of protection from scuffs and wet weather. The slipcase can also be used alone when transporting a netbook between classes or meetings.
