The tri-blend shirts are a unique and proprietary blend built from 50% Repreve polyester from recycled plastic; 25% organic, US grown, combed, ring spun cotton; and 25% TENCEL Modal. These sustainable fibers combine to create a soft, flexible, and smooth fabric which looks good plain and holds a great print. Each shirt uses 6 recycled poly water bottles and all fabric is spun, knitted, processed and finished in the USA. They are also cut and sewn in Haiti.
