I sweat a lot, especially at work (retail) so I started carrying an old microfiber towel in my back pocket to dry my face. However, it always piled up there and the fabric was so thick that I could feel it all the time. I've decided that now is the time to get something really suitable for the purpose. The colors and patterns on them are great and they have a nice look that isn't too flashy. The fabric is quite thin so they lie flat in my pocket and don't bunch up even when I have to put other things in the bag. They're also quite large, which turned out to be a plus; I can wipe the sweat off my face, fold it, and it has a fresh side, enough time to last on a hot day. They wrinkle a little when washed, but if you just flatten them out with your hands, they fold up easily and stay flat enough for everyday use. It's really not a problem if you don't want to stand out or the crumpled fabric really bothers you. All in all these are great handkerchiefs and saved me all those hot months!
