Ekahi means "one" in Hawaiian and this is the one and only collared shirt you'll need. Masculine doesn't begin to describe how awesome the shark-wave design looks against the crater dyed material. Made from 100% combed Peruvian cotton for the comfort you expect from a casual shirt and the substance you want for a refined sense of style. The unique color comes from our specialty dying process that uses real volcanic ash. Plus, it is proudly embroidered in the United States using with soft backing and threads that won't bleed during wash for quality you can see and designs that stand the test of time.
