The Wanderer is made of Waxed canvass and has waterproof zippers as an upgrade. Carry your precious items in wet conditions without a worry. The Bag has external measurements of 20.5 inches long, 11.5 inches tall and 4.5inches deep. The carrying strap is made from seat belt webbing and is fully adjustable to fit the petite and the brawny users. On either end of the bag are pockets, one, zippered and flap closed, that expands to carry a water bottle. And the other end features an open stash pocket that could hold a small umbrella, med blowout kit or 2 AR mags. The flap that covers the body of the bag is secured with 2 magnetic snaps that seem to find their home without even directing them where to go. On the this flap you will also find the beloved GGG skull Icon on a leather patch. The flap itself has storage on the outside. 2 9X5 inch zippered pockets are lined with a soft tricot fabric to ensure that your glasses, jewelry, smartphone or other delicate item remains unscratched. Upon opening the flap, you are greeted by the Grey Ghost Logo on our woven label. The front of the main body features two vertical zippers that when pulled down opens a gate that allows the user to get to smaller items that you would need on a journey of trip to the office. The reverse side of the gate has two zippered pockets to organize loose small items. On the back wall of this compartment are 4 varying sized pockets, made of stretch mesh, for securing larger items the size of back up batteries and rifle mags. There is also a pen pocket to carry the "stabby" pen. On the very top of this part of the Wanderer you will find a 14 inch zipper allowing you to access a generous pocket that would carry an iPad Mini sized device..
