"My white coat is now grey! Help!"に関する回答Hey Cate - here is the answer from Patagonia on dry cleaning, this was taken from the Care Guide posted on patagonia.com and ifixit.com Dry Cleaning Given the rumpled nature of the road trips that inspire so much of our gear, Patagonia doesn’t make anything that requires dry cleaning. Our clothes are made to be worn and washed with very little fuss. More importantly, the EPA estimates that 85% of the dry cleaners in America use perchloroethylene, or "perc," to clean garments and textile products. This chemical solvent has significant human and environmental risks. We make clothes that wear and perform beautifully without all that.
