Support a great cause and add a classic piece to your wardrobe. Designed after the original vest Hiram Bingham wore on the 1911 discovery expedition to Machu Picchu, our handsome rendition is knit of soft tweeded alpaca, with a v-neck, double patch pockets and plaited ribs. All proceeds benefit a new museum and research center in Cuzco jointly operated by Yale University and the University of Cuzco for the conservation and study of the Bingham collections.
