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.
If you are just looking at the picture and planning to buy, then I recommend to stay away from this. The quality of the product is not up to the mark. I purchased van heusen along with this and honestly this doesn't stand a chance in quality. The material is on the lighter side and not as thick as other brands. I purchased this one on looking to the reviews and Im disappointed with the final product and I won't recommend to anyone.
