Woven into The Hub snowboard jacket are electrically conductive fabric tracks that connect the chip module to a fabric keyboard and built-in speakers in the helmet. The chip module contains an MP3 player and Bluetooth capabilities from which the snowboarder can control a mobile phone. When the phone feature is used, the stereo system acts as the headset. The microphone is integrated into the collar of the jacket.
