Our signature Jonquil yellow lining is 100% cotton duck with pure finish. It is made from America Cone White Oak Denim and produced by a New York manufacturer with over 80 years of experience in producing high quality fabric. This manufacturer has worked with a prestige dye house that has been in existence since 1838 and is well-known for its ability to create highly saturated colors. Cotton duck, known outside the industry as canvas, is a heavy and durable cloth, woven with two-ply yarns in the warp and a single-ply yarn in the weft. Its sturdiness and longevity makes it the perfect lining for frequent-use bags.
