Flexfit baseball caps or snapback caps with a straight brim are unisex. Just choose a design and you can go. For girls, men and youngsters, for those who have a taste and for all whom this style suits. When the wind starts whistling, choose a beanie, put up a neck gaiter and you will be at ease again.
Beautiful scarves or fabric face masks are beautiful designer things, you can throw in a key ring and you are done. Go for it.
