I walk every day in the woods no matter what the weather. I go for an hour or two. The weather can be nasty here on the Illinois, Wisconsin border. In cold weather, almost every day from November to April, I've worn one of these for over 6 years. No matter the wind, sub zero temps, sleet, snow, or what ever this cap will kep your head, ears, cheeks, & neck warm and dry. The flaps snug secure with velcro to keep out the wind. The bill keeps the sun out of your eyes and the snow off your face.  The lining keeps ypu warm. THe material on the outside keeps you dry.  Can't beat it. With the flaps up you may look a little goofy but I'll sacrifice looks any day to stay warm and dry.
