The lightest and most compact "washing machine" in the world, the Scrubba wash bag will give you a machine quality wash wherever your adventure takes you. At only 145g, it can easily be added to any backpack or suitcase without taking up crucial space. Fill with cleaning liquid, water, and your clothes then roll it over and clip to seal. Use the valve to let out unwanted excess air. Once the air is out, you'll be able to press down and scrub your clothes over the inner washboard for 30 seconds to 3 minutes. A transparent window lets you monitor the entire wash process without having to open the bag. Once the washing part is done simply open the bag, rinse your clothes with fresh water and hang to dry.
