The Co-Driver bag from Sabelt is designed for rally navigators, but it makes a very smart briefcase for the driver's paperwork as well.
The black ballistic nylon bag measures 14 1/2" Long x 11" High x 2 1/4" Deep (365mm L x 280mm H x 57mm D). The main compartment has a flexible divider to keep your course notes organized. A full-length zippered compartment (below the horizontal zipper in the photo) can hold a few sheets of letter-size paper, and a smaller zippered compartment (to the left of the vertical zipper) can hold a log book or half-page notebook (approximately 8 1/2" x 5 1/2"). Two loops and two pockets on each end hold pens and pencils.
The vertical pouch on the left has a hook-and-loop closure and is just the right size to hold a cell phone or a stopwatch. The sturdy main flap closure is held securely closed by a full-length hook-and-loop fastener and has a single carry handle. The back of the bag has 5 full-length strips of loop fastener, and two full-length strips of 2" wide hook fastener (included) let you secure the bag to the rollcage, door bars, or even your harness.
Black nylon with a single black-on-yellow Sabelt logo on the top flap and silver Sabelt logos on the zipper pull tabs. Weighs approximately 21 oz (590g) empty. Sold individually; accessories not included.
