CTB20 is acclaimed for offering a swath of utility-forward travel features in a mobile, everyday size. We took its modern DNA and infused it with a custom-made, high-end cotton & wax-finished shell called P400 Wax C4X.
The waxed canvas was developed with the historic Scottish mill Halley Stevensons. It is stiff, durable, and designed to get better with age. We added leather zipper pullers sourced from 100-year-old supplier Berger Co. Combined with our standard gray internal lining and the CTB20’s signature features set and appearance, this heritage variation is built to make its own legacy.
