When you’re surfing or camping in that remote place with no available facilities, there’s not too many ways to rinse off. This portable water pressured-powered shower by Helio solves that exact problem. The way it works is via a pressure foot pump to maintain the water pressure instead of having to place the water storage section above you and rely on gravity. The amount of water should be enough to last for an entire 5 to 7 minute shower, which should be plenty. Made by Nemo and available on Amazon.
