The mask will allow you to breathe comfortably thanks to its cotton soft textile. Size is unisex, so both men, women, and kids can use it. Adjustable for ears with elastic holder and adjustor. The ear loops are approximately 8-10in long and they are elastic. Therefore it can be easily stretched if your head size is a little bit bigger or if you want to use additional back to head holders.
