I wanted to like these, but...
These are certainly small and lightweight, but if you are traveling to a location with complimentary shampoo I recommend just using the shampoo to wash your clothes. Most plain shampoos work very well as a laundry soap, but I'm not sure about the type with conditioner.  I had some pretty dirty hiking clothes and the shampoo seemed to get them cleaner than this soap.
