I haven't actually used this- I only know it smells great. I actually bought it when I travelled for work intending to wash tights with it while on the road, but I quit that job.
My boyfriend was leaving on a month-long backpacking trip to Europe so I gave it to him. He gives it an A+! Save the space and weight in your bag and bring this baby and a little clothes line. Want to wear your favorite shirt twice on a sweaty, tropical vacation? Easy.
