Solar shower 20 liters

20 litres. Black.
Free hot water using environmentally friendly solar energy. Even when the sky is cloudy, the water in the 20-litre bag heats up to 40°C.
The bag is not printed in black on the back to ensure maximum rapid heating.
Unlike the generally transparent versions, algae no longer form because light cannot penetrate the bag.
It can be operated lying down and hanging.
Two shut-off valves, one directly on the bag for safe transport and the other on the shower head for added convenience.
