PackingLight strongly suggests travelers plan on performing laundry duties in order to pack less clothing. The Lewis N Clarke Woolite brand Travel Laundry Soap is the original cold water wash soap made specifically for hand washing fine fabrics. Well, we don't know if you are packing the fine fabrics, but Woolite works terrifically on most any fabric and particularly well on quick-drying travel clothing. Ten packets of .25 fl. oz. Woolite are provided in this package. Imagine washing two or three garments with one individual packet. With the packets of concentrated Woolite offered here you might be able to go ten days.
