Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
It is a genuine item. On Carhartts website the thicker beanie is now discontinued (has been for over a year). Quality and materials are the same. Great item great price, its just too bad i lose them too often!
