I use mine all the time in the garden on sunny days... keep one in my hiking pack too.. just seems like a handy thing for first aid and other stuff as well
Pillow, head/face shield, towel, rag, pot holder, tinder shaving holder, wet it and pop your camping buddy in the ass. That's just the things I've used it for.
I have a few. One in my bag that I carry everyday. Use it for a few of the things previously mentioned as well as some others I imagine. This one here was a "free" gift from a purchase a while back and I just hung it here.
