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.
O'Neill just unveiled the Hub snowboard jacket with an integrated MP3 player and Bluetooth. You can listen to tunes or use the system to talk on your mobile phone.
