Classic shot Harris!
Interesting thing about the use of speed suits in World Cup racing is that snowboard cross consciously wanted to keep the look of their non-FIS counterculture. The ski cross people look to be leaning the same way. Ski-mo, telemark and to some extent XC and bicycle racing suits do raise eyebrows outside of the fans of the sport. Guess its the boots.
I suspect the popularity of ski-mo runs parallel to XC, closer to a european appreciation. Schedule a telemark or snowboard comp on a powder day and you'll wish you spent the money on yourself.
