I have often thought that such a suit would be neat. but have never experienced one.
The closest thing that I have experienced (As a head covering) is a halloween 'Grim reaper' hood. this had a see-through black material that covered the face. I found that with the black material it obscured the view a surprising amount so that even in low light, as may be encountered at a party or even outside in the evening, one could hardly see anything at all.
Another caution is that if you intend to wear this outdoors some cities have laws or rules against 'Masks' and a fully covered head would fall into that category, so either check your local laws, or avoid your local law enforcement personell. (Note I'm trying not to refer to Texas here)
The suit looks neat, and I envy you for haveing (Or going to be having) one.
