The Gitman Vintage x SMOCK Camp Shirt in Navy. Smock has teamed up with Gitman Vintage – a NYC-based American men’s shirt maker since 1932. We have used their masterpiece camp shirt pattern in a long sleeve version with exclusive premium cotton twill fabric. The brown marble vintage shank buttons are hand-selected and carefully sewn by hand. All the details work in concert to make the shirt a must-have for the season.
