I thought that "transparent latex" is indeed transparent and you could see through it. No.
I thought that the condom could be used with the pile of gags I have. No.
I thought that I could I stuff the condom with pantyhose to make an effective gag. Yes.
I thought that I could sleep in this hood. No.
It fits very tight, but the problem is with the nose holes. The placement and the distance between them are not correct, so breathing is very restricted. Any additional device (e.g. gag) leads to further displacement of the holes, completely blocking the airflow.
Probably, the condom can be used for a decently sized cock. Could not prove or disprove this statement so far ;-)
