I bought the hood many-many years ago (~1997?) in Expectation in London. That was my firstlatex mask ever, bought during my first latex shopping ever! Since I had no experience in hoods, I forgot to have a look at the size. Apparently it's either "L" or "XL", when my usual mask size is "S". However, the mask is quite comfortable, so I often sleep in it. The gag is also not too intrusive, even when moderately inflated.

10 years after I finally torn it. I was in a business trip and was going to sleep bound while wearing this hood. Since the hood was big, I did not lubricate it. As a result I'm going to try to make it a couple of sizes smaller...
