I am a professional space adventurer and can positively say that this product cannot be used in actual space expiration. That being said, I am however in a space rock group. I bought this product for my band's super space jams. The visor is a bit dark so I am unable to see my sweet finger licks through it, but it's cool because I can play with it up. If I would have designed this helmet, it would have a voice modulator and walkie-talkies...and then i would buy 5 and give them to all of my space friends.
