If you have business to do and carry a 12", 15"or 17" laptop, then you are in need of the Tenba DB-15CL. If you have an Apple iPod& or MP3 player, then stash it in its own secret pocket between the straps. If you have the iPod remote controller, then attach it to the strap and control your music from the shoulder strap. Our leather-trimmed mobile office backpack has a lot of space for business papers, office accessories and even a small digital point-and-shoot camera or mini-DV video camera. Expands by 2 1/2" for those big days and can even hold a small digital projector in the main compartment. The side compression straps also double as luggage cart straps and attach to your rolling luggage handle. Elegant and cool, the DB-17CL is the perfect companion for a business meeting or grooving while commuting.
