A whole jing-bang of my friends recently went on a trek 18,000 ft above the sea level. On returning back from the journey I asked one of them what he missed the most up there and he almost instantaneously replied, âa hot water showerâ. I plan to do the same trek next year and the only difference is that my reply will not be the same as his for I would have the solar powered Stearns sun shower to assist me up there. It is capable of filling up 2.5 gallons of water which means it is good enough for two to three showers. Also, all it requires to heat up 60 degree water to 110 degrees is three hours of solar energy and the micro-cell foam insulation ensures that the water stays warm enough for long durations. Its light weight ensures that you donât feel the burden of carrying it other than the weight of the water of course. At the end of it all, carrying water on your back may sound stupid to you but then try doing a high altitude trek and I would want to know your answer when you return. And, if I tell you that it merely costs $22.90, you would stop thinking and buy it almost instantly.
