They have been unveiled here. Ralph Lauren again.
Actually, I like this one and think it wouldn’t be that hard to knit one that is very similar, less the polo thing, of course.
In addition to this beret, there is also a knitted cap with moose (plural) on it too. http://www.nbcolympics.com/photos/galleryid=365558.html?chrcontext=teamusa#opening+ceremony+uniform+unveiled
I think I’m going to try to knit up a similar jacket to this one. I like it. Plus I can embroider some sort of similar symbol too. (I am a professional digitizer for embroidery) Can’t use the polo logo, but I can come close enough.
