Get twice the organizational potential! Patent-pending Z-system provides dual sets of D-rings, pockets and pouches, essentially two separate binders in one unique package, where each side mirrors its opposite. Color-coded accents allow you to distinguish each of the two mirror images at a glance. Innovative, segmented design lays fully flat regardless of which side you wish to access. Zipper closure protects all contents safe from the elements while keeping loose items from slipping away. Puncture-resistant ripstop nylon covering features a square pattern that keeps tears from spreading. Rigid interior boards help prevent individual sections from buckling and warping. Handle and shoulder strap provide briefcase or messenger-bag transport versatility.
