If necessity is the mother of invention, then the Scrubba® wash bag is born a clever child. Imagined and designed as a space saver for an expedition to Mount Kilimanjaro, with a need to launder apparel in limited luggage space. It satisfies the needs of the habitual runner/traveler just as well, with its ability to accommodate very small to medium sized laundering, quickly and effectively.
The design and use are intuitively simple. A bag holds the clothing, detergent, and water - extra space is removed by expelling air from an external bladder, and one internal surface has a washboard texture to scrub a foamy lather. Roll it in a towel, wring, then hang dry and and your gear should be good to go for the next run. My experiences allowed one outfit to manage a five day trip, with everything fitting into my carry-on roller bag.
