“Nothing about sizing listed in the description, assumed a one size fits all. However if you read the questions one of the answers to that you need to write your size in your purchase comments section. This answer implies that there is a small and large option available. I bought XL socks and received (I assume) a small mask (that I ordered assuming on size fits all). Come on Akesco you can do better. Include sizing selection on the product page (as per yours socks). Or at least mention sizing options and instructions in the description. This small mask I've received is not going to fit many adult males.”
