This V-neck waistcoat is made of sea island cotton, called "Gossypium Barbadense". This yarn grows only in the best climatic conditions and is grown exclusively in the Caribbean islands of the British West Indies. WEST INDIAN SEA ISLAND cotton is hand-picked and contains the longest fibers in the world. Resistance, brilliance and silkiness are guaranteed by the fineness of the fiber and by the micronaire around 3.0. The rigorous control system guarantees the authenticity of the raw material. The braided pattern creates an iconic three-dimensional effect along with the delicate contrasting details.
