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.
Not good value at all, I bought a Gildan one which came the same day for about three quid and it is better quality to be honest. Also the sizing is very small. I had bought these for a relative but will probably just wear them myself as don't think they will be big enough!
