This face mask is made of 250g soft knitted polyester and is with soft elastic ear loops. It is thicker than our other types of fabric masks as it is double layers (one-side print). Please be noted that this is NOT a medical rated mask, it is meant for everyday civilian use. And it is not recommended to wear a face mask while you are doing exercise. The ear loops are adjustable, soft, and comfortable to wear. 2 colors are available, black and grey.
