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.
After reading customer reviews, I decided to purchase one size larger than normal. The fit is perfect, the fabric is lightweight but durable. The sleeve is a nice length to cover "arm flab." These are perfect for hot weather.
