My very good friend Rudy Duong, who happens to be one of the old school Lisses guys from back in the day has just launched his own brand of Parkour clothing, after 4 years of hard work to make it happen (an obstacle course in it's own right !).
His dedication to staying true to the original Parkour spirit and values no matter the amount of efforts it involves is, i think, of great contrast to a lot of the crap you see commonly today.
If you want to read more, you can check out his website here: http://www.traceur.com/en/
(though mostly in french, there's some videos for the uninitiated ;) )

Good luck Rudy !
