Tin Cloth is a tightly-woven canvas duck coated in paraffin wax for superior water resistance. The back panel and base are made of rugged 2-ply by 3-ply Rugged Twill for added strength and endurance.

The shoulder straps are padded with Tin Cloth and lined with Moleskin to reduce slipping and increase breathability. The adjustable straps are contoured and attached to the backpack with vegetable-tanned Bridle Leather from Pennsylvania's Wickett & Craig tannery, known since 1867. Our Bridle Leather is treated with bark-tannin solution, and tallow and wax are added for flexibility and shine. This makes it suitable for both our luggage and equestrian equipment.
