Our long sleeve is made of a tri-blend (50% polyester 25% combed ringspun cotton 25% rayon) that is incredibly soft to the touch and will not shrink (It is pre-shrunk). Our long-sleeve is sweatshop-free and child labor free, we take social responsibility to the next level in everything we do. Alongside that, we worked with manufacturers that upheld the highest quality practices and highest ethical standards.
