The outdoor shower bag is made by environmental friendly materials which are safe to human health. The bag itself will not leak, and the faucet can be tightened by itself. The water outlet at the top should be plugged tightly to prevent leakage. This jumbo size bag can easily carry up to 10 GALLONS. Enjoy a nice and refreshing shower when rafting, outdoor camping, fishing, hunting or in the wilderness. You can also take this to the beach in the summer and wash off any salt water after swimming.
