This is one serious piece of kit.
The hood has internal padding and a small hole for breathing. The straps can be pulled tight to give a really snug fit around the head. And if you add padlocks your sub knows that hood is not coming off! I can attest to how great this hood is because I own one and have been put in it many times. I always struggle to hear anything when I'm wearing it. I end up saying 'Sorry Sir, I cannot hear you' when all I can hear is a whisper. Pretty sure my captor is talking at normal volume too. It's a head cocoon which blocks out everything, the only thing you can hear is your own breathing. It's actually incredibly relaxing as well as horny! Seriously fun!
