Long John Pants – New Trend?

H&M has introduced their new line of clothes for fall/winter, and they include - wait for it - long johns for men to be worn as pants.  According to MSN, "the $39.95 revitalized long johns are part of the Swedish retailer’s new Mauritz Archive menswear collection."

I am not going to lie, I love wearing my long johns in the winter.  BUT, I do it in the comfort of my home, or under my ski pants at the mountain.  Is this a trend you or your guy would wear?
