Familiarity: I gave it as a gift but have feedback to share
I wear this hat on super cold ( <10 degree) days under my helmet and it keeps my head nice and warm. It fits really well under my helmet (anon) and also looks good on it's own. I also really like that this hat folds down really small to be stashed in a pocket.
