To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
My sons wear this product for swimming practice 2 hrs/day for 5 days/wk. This product started deteriorate within 2 weeks. Just a little over 2 weeks it all became saggy and thinning out. Should have listen to the previous review's advice. Will not buy or recommend this product.
