100% Peruvian Cotton, softly structured, heavyweight (heavier than a tee shirt, but not quite a sweatshirt).
Machine washable.
All of Nation's Heavy Slub garments have been pre-washed and dyed to reduce shrinkage. To prevent slight shrinking, air dry or dry on a low setting. We also recommend washing these items separately from abrasive items like denim, towels, or items with hardware (zippers, buttons) as it causes unnecessary wear and tear.
