I would think you'd be better off with at least two sets of clothes**, make sure they are ALL synthetic so they dry quickly, and then rinse them in water - with a tiny amount of soap (I use a tiny bottle of camp soap).


**In cold weather synthetic long underwear plus shorts makes a good second set of clothes, though its not very fashionable - you kind of look like superman. Of course it also can keep you warm.

In summer, a synthetic t-shirt and shorts work OK as a second set.
