Wow.., this is absolutely the most gorgeous map case we’ve ever scored! Made of heavy canvas, with all edges reinforced with nylon tape. Has two compartments, with a semi-stiff back. An additional pocket is sewn under the flap. The flap is long enough to secure the load, when filled to capacity, and has a leather strap closure. Of course there’s an adjustable nylon shoulder strap. Measures 11” x 9” x 5.5” fully expanded.
