My son is a Marine deployed to Afghanistan and conditions are HOT HOT HOT with little opportunity (or time) for showering. Wet wipes are okay but water to actually rinse away sand and dirt is what my son wanted. I found a $43 solar shower at a camping supply place and then a friend found this online... I ordered four of them and shipped them three days later. It took over two weeks for them to arrive but they were the most popular box in the company that day! It's hot enough that 5G water is good for a shower pretty fast and every guy in the company got a shower that first day... I got a great big thank you and was thrilled. I'm sending four more as soon as I get them!
