Vans Team Riders Mark Landvik and Jamie Lynn are featured in Volcom's new Thermal Defense System (TDS™) video, helping to explain the science behind Volcom's new outerwear technology. Volcom spent months of research in the field with riders like Lando and Gigi Ruf to development the new system, which distributes body heat and uses strategically placed insulation to keep you warm and dry. The video has plenty of powder shots from the boys testing out the product in some of the harshest environments in the world. If it's good enough for these guys, it must work for mere mortals like the rest of us. Check it out, and visit the Volcom Snow Team Page anytime for exclusive content like this Mark Landvik Interview.
