Tom Bihn (http://www.tombihn.com/) has introduced the Cadet, a laptop briefcase designed for Apple laptops — including the 15-inch MacBook Pro, 11-inch and 13-inch MacBook Air and the iPad 2.

The Cadet is designed to carry your laptop or iPad, a few files or magazines, power supplies, pens, notebooks, and other small accessories. It’s a checkpoint friendly laptop bag: using two clips, the botton edge of the Cadet Cache attaches to two vertical pieces of webbing sewn into the Cadet.

The Cadet is available in two sizes: 15/13 and 11/iPad. Both sizes feature a removable protective laptop sleeve (called the Cadet Cache) in sizes designed specifically to fit Apple laptops and the iPad: the 15/13 size fits both the 15-inch and 13-inch MacBook Pro, the 13-inch MacBook, and the 13-inch MacBook Air, while the 11/iPad size fits the 11-inch MacBook Air and the iPad/iPad 2. In addition to a laptop, the Cadet can also fit an iPad or iPad 2 with or without a protective case or sleeve.

The Cadet is US$170 and includes the Cadet Cache protective laptop sleeve and Standard Shoulder Strap. It’s available for pre-order in colors Black/Steel, Black/Iberian, Steel/Solar, Forest/Steel, Navy/Solar, and Cardinal/Steel and ships by mid-to-late November.
