Hi - we ordered 2 masks. The gentlemen's mask is very nice and a reasonable fit. However when my wife opened her mask and offered it to her face it was immediately apparent that it was far too small to fit and adult's face correctly - it's size appears to be suitable more for a child or adolescent. We were about to send her mask back for a replacement, when we noticed a small note on the plastic bag stating that if opened it could not be returned due to health and safety. We feel this warning should have been more prominent - and perhaps the item's description should have stated that the size of the mask might be an unsuitable fit for an adult's face. Had that been stated we would have selected something else. Disappointed.
