Interesting reactions. I guess this is just a style I've seen aound -- on Bobo, those pictures of rock climbers that robin posted a while back, various Japanese brands. In my mind (only in my mind?) it isn' t really farther "out there" than, say, fair isle. I'll probably wear it with some outdoors-y stuff. Maybe a down parka, straight leg jeans and quoddy grizzly mocs.
I don't dislike it, and in the context you mention, it could certainly work. If I were to wear one, it would have to be in totally boring colors--navy, tan, cream, maybe green.
