I have six of them and use them all.Always have one on me and can be used all year long.Can even be used as a face mask,balaclava and neck wrap along with the various configurations for around the head.
I find mine very useful especially as I do not always have a winter hat with me but the wrap is compact enough to carry everywhere.Can't be used as a sling though(at least I haven't tried)
and like was stated earlier comes in limited colors.All in all I find it more convenient than a bandana since it has multi-season capability.
