I have several of these. Super thin and light, they dry very quickly. I use them for hanging at the beach and pool, and as sun protection while sailing and stand up paddling. Unlike cotton, they don't feel icky after you've been all hot and bothered, so you can use them for several days while beaching it, even if you fall in the water. Just rinse it if in fresh water if used in salt water so it is a bit more fresh for re-use. Only negative- they seem to get stained by my sun screen.
