Made with the highest-grade fabrics, leathers, and manufacturing, our Rugged Twill bags will last for generations. The unique dense cotton twill fabric is tightly woven and lightly waxed to defy weather and wear. Bridle Leather, slowly vegetable-tanned in natural plant solutions, molds itself to the contours of hand and shoulder. Stitched with industrial strength bonded-nylon thread, all interior seams are bound with Tin Cloth to ensure lasting integrity. Classic lines, traditional craftmanship, and problem-solving engineering are the hallmarks of our original Rugged Twill bag.
