100% Peruvian Cotton, softly structured, heavyweight (heavier than a tee shirt, but not quite a sweatshirt).

Machine washable. All of their Heavy Slub garments have been pre-washed and dyed to reduce shrinkage. To prevent any slight shrinking, air dry or dry on a low setting. We also recommend washing these items separate from abrasive items like denim, towels, or items with hardware (zippers, buttons) as it causes unnecessary wear and tear.
