I bought this about 10 years ago and used it 2-3 times. I don't see any noticeable stains. This poncho can completely cover your body even while wearing a large pack. It uses a thin, lightweight material for a supple feel. The large opening at the hem makes it less likely to get stuffy, and it's useful as rain gear for hiking, walking, outdoor festivals, and more. You can also use it as a tarp by threading guy lines through the holes at the four corners. Thank you.
