Evolved from the raw essentials of adventure and American heritage, the Will Leather Goods Signature Leather Collection uses only the richest vegetable-tanned bridle leathers, sturdy 18 oz. cotton canvas, 10 oz. twill backing and steel-molded hardware. Oils and fat liquors used in the leather tanning process not only give the hide its supple appeal, but also imbue the elements needed for the leather to remain soft and durable over the life of the bag. On occasion, the oils will rise to the surface of the leather – this is a sign of the quality of the leather; simply wipe with a soft cotton cloth to rub the oils back into the grain to care for the bag. While an average bag takes 75 steps on a factory line, a WILL bag undergoes an average of 159 steps. We take additional steps for extra rivets, reinforced leather corners and box stitching to ensure we offer a product that will stand the test of time..
