This shirt is made from long grain, GMO free Peruvian cotton. Peru is the only country in the world where cotton is picked by hand on a large scale. The 4,500-year-old tradition prevents damage to the fiber during the picking process and removes the need to use chemicals to open the cotton plants before harvest. This environmentally friendly process results in cotton that is soft, strong, and lustrous – and the tee will get even softer with every wash.
