Waxed Canvas: 10oz cotton canvas, waxed with a raw beeswax from USA bees (from a farm in Michigan). The fabric is then baked so the wax absorbs into the fabric giving it some water-resistance and added durability. Waxed canvas wears/ages similar to leather. USA Vegetable tanned, full grain leather. Full Grain leather is the highest quality leather and will age, rather than wear out, developing a much sought-after patina and unique character.
