I think it's been out for ages but very few people stock them. My OPD was given one to use for himself and he was unimpressed, so I think he chose not to stock them.
I've seen an extremely attractive girl at school with one of those on her head, so I asked her where she bought it caus' I really wanted one of them. She told me that an Oakley rep just gave it to her at some ski resort in Québec because she was a great skier. Lucky girl...
I have one - it's very "stretchy" and has all kinds of Oakley gasses names and insignias written all over it - it's extremely cool - I wear it constantly but have never seen another one anywhere....
