Our new Weatherproof bags are made with a proprietary leather that’s vegetable-tanned by Wickett & Craig, the 150-year-old Pennsylvania tannery that makes our Bridle Leather. We worked with our longtime partner to develop this special boot-grade leather that is weather- and salt water-resistant, then added solid brass hardware and a wool felt-lined shoulder strap-pad for comfortable carry. Modeled after our most popular briefcase, this bag features two internal dividers to keep tools and electronics separate.
