With design experience spanning 18 years in marine and outdoor gear design, and an additional 20 years at nanamica, Eiichiro Homma understands necessity rather than outright functionality. The Button Down Wind Shirt adopts its five-button front and curvy hem from vintage shirts from the 1950's to 1970's. Its unique Oxford cloth blend of CORDURA nylon and organic cotton ensures that it is just as durable as it is soft and breathable. 55% CORDURA Nylon, 45% Organic Cotton, Button Down Collar, Button Closure, Chest Patch Pocket, Embroidered Branding, Curved Hem.
