Outdoor Products 40 L Valuables Hiking Dry Bag, Watertight Roll Top Seal, Red, Unisex, 0.92 lb

if it's not possible to hang dry the clothes, store them in a waterproof roll top bag like this until you can get them in a dryer or the sun. I also use little 1/2 gallon rolltop bags to wash my clothes in the gym shower. much easier than bringing a bucket in
