S.O.L. Solar Shower (20L)
There are lots of solar showers out there, but this one has a built in thermometer on the bag! Fill the bag with water through the front cap, place in the sun with the black side up, and when the water warms to your liking hang the shower above you and enjoy. You can adjust the water pressure with the flow-control shower head, and the shower bag has a front mesh pocket to stash your toiletries or mirror in for easy access while you bathe.
