Aspero is a naturally occurring wild cotton that is found in the foothills of North East Peru: being a tree it is not farmed and is one of the purest, most organic kinds of cotton available. As it cannot be mass-produced it has been highly prized for generations by the indigenous Peruvian population for its qualities of fineness, softness, volume and also strength
