Full grain "cowboy" or saddleback leather is a thick type of pull up leather often used on horse saddles and work boots. It is designed to last in extreme conditions and for protection. Oil is applied under pressure at high temperature to achieve a rugged finish. Crazy Horse leather is ideal for men who like want a more masculine, rugged looking bag that holds up well in moist or dry climates. After years of wear, this bag will have a distressed leather look and become quite flexible, yet maintain its protective nature.
