Custom developed with Kurabo Mills, Japan. This is fabric our original prototypes and first pants were made from. The ultimate twill is more than just a clever name. When we set out produce pants that that took the best features of chinos and denim and marry them into something better than the sum of its parts, we knew we’d need a twill that offered the fit and feel of a traditional chino twill but also the durability and “wear-to-fit” characteristics of denim. The ultimate twill achieved this and has outdone even our best expectations. We’ve sold and shipped countless pairs of ultimate twill pants around the world and even some of the first pairs we ever sold are still being worn today.
