The Shower Kit is a mix of water, shampoo, and conditioner. When watching an ISS video of astronauts washing their hair, all of the shampoo, conditioner, and water tubes were floating everywhere. Well now all three separate tubes are attached and there is a towel clip. That way if you would like to have a towel, just unstrap the Velcro and a clean towel will roll out. In one tube there is water, the second tube has shampoo, and the third tube has conditioner. Now there are four everyday items in one object.
