Yeah, I couldn't understand what the guy would be using it at during dinner. If this is a real product, it's not even well thought out. The times you would use this, you are probably pretty cold. Myself, when I'm cold, I tend to have a stuffed up nose. So how does this keep me from breathing stale air? Plus, some people just breathe out of their mouths when they sleep. How hard would it have been to just add a slit for the mouth?
It's true, it is sold at Amazon. http://www.amazon.com/The-Face-Blanket-Royal-Blue/dp/B00S31NXO8/ref=sr_1_2?ie=UTF8&qid=1423432243&sr=8-2&keywords=face+blanket This doesn't mean it's not a joke, but at least it's a real product.
