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.
Could be warmer but I’d wear snow trousers in 10 degree weather so I might be an extreme case, it’s a lovely jacket, Didn’t realise it was rage blokes version but I’m a size 12 with an hour glass athletic figure. It fits fine. Very comfy and easy to wear.
