A slight variation from the inhaler - My son wrestled an opponent who wore a full face mask. I understand this requires a doctor's note and is usually due to having a broken nose. He said it was virtually impossible to have an effective cross face against someone when they are wearing a mask. This wrestler had to stop several times in the course of his 3 matches to adjust or re-attach the face mask. He and his coach were quick to fix it and it looked to me like the wrestler was frustrated with the mask malfunctions. Later when I voiced concerns about the delays and opportunity for resting and coaching advice, my son pointed out to me that this wrestler had to breathe through 2 small holes in the mask. He didn't think it was an unfair advantage. I guess he told me!
