This may be a stupid question, but I can't seem to find a easy solution. Last summer I rode most of the Trans Missouri Trail. Between getting stuck in 100 degree weather, sweating, and falling in some low water crossings I didn't smell good by the end of the day. I thought I would be smart and put my dirty nasty clothes in some walmart plastic bags to keep them from the rest of my clean clothes in my dry bag. At the end of the next day I opened my dry bag to find that the smell of my clothes from the day before have straight stunk all my clean clothes up. My question, on a multiday trip, how do you keep your dirty clothes from contaminating your cleans clothes while stored in the same bag?
