This is a great product. I live in the Pacific northwest, so our winters aren't too crazy, but they do average in the mid 30's to high 30's usually. I always keep this beanie in the pocket of my jacket, for when i get cold I just whip it out.My skin is usually pretty sensitive but none of Ice Breaker's stuff really bother me that much. And as always, with merino wool, it doesn't smell. Remember if you buy something synthetic it can get smelly pretty fast.Two thumbs up!
