When I pull the hood of my rain coat up I can't see a thing and it blow off in the wind unless I pull the cords of the hood tight around it giving me no vision at all.  I live in a very rainy area and the dog must be walked regardless of weather.  This is a great little hat.  It folds up easily into my raincoat pocket when not in use.  Stays on my head in fairly strong winds.  Dries quickly.  I have a large head and was a little concerned about one size fits all, but it's perfect.  I wonder why I didn't buy this years ago.
