Bob, I agree. I have a shower tent as well, although not a pop up one. Have used all the other inexpensive types of shower fixes also, the Spray bottle, useless. The garden sprayer hand pump, useless. The bucket in a tree, useless. Now the
solar bag shower is Okay if you have something to hold a 2-5 gal of water bag up, ha, it's heavy and never gets warm in the mountains where I live. And a tarp strung around trees for privacy doesn't always work either. Ask me how I know...
