Genuine nappa leather blindfold with nose opening and lacing at the back.
Due to the wide band around your head and only the nose cutout, you really can't see anything, but it does not hinder your breathing or nose.
Of course you could pinch the nose closed for an extra sensation, or put a nose hook on it (one of the advantages of this eye mask). Another advantage is of course that it really fits almost everyone due to the wide leather strap. and the lacing at the back.
