Tank is a “tuff as nails” messenger style bag that can hold a letter size notepad with a clipboard… and lots more! It features a large exterior pocket for a large phone and case as well as a large inside pocket. Tank is built using this very cool shoulder of vegetable tanned leather from Mexico. The leather is heavy and thick at 7 oz… pliers were used a lot when hand stitching the bag! It also has a inner coating that acts like a liner for the bag. It comes with a shoulder strap.
