I see those all the time and I wonder if they really work?
Ha! It certainly got my attention :-)
The reviews are actually decent. I think a lot of people use them for camping.
I haven’t camped, in years....but....if the grands start playing soccer, or any other outside sport....may have to look into to. I can still see my dear MIL sweating it out, at all of our kids’ outdoor games 🥵
