http://mpora.com/videos/3Cbp0IP3H Markus Keller is the star of the latest in the Access All Areas series, made by our friends over at Onboard Mag. Here he takes you through he pre-season shred routine, which seems to include some rad runs through the Laax halfpipe, a bit of pissing about on the edges of the pistes, and… losing his trousers at a party in New York. Nice warm-up!
