Ya me too - i got the co-op with skullcandy in the sleeve, but wondering what to put in the collar? Skullcandy has to make something right, i will investigate.
haha ive always wondered this, never figured out how it would work that well though. you'd have to have loud ass headphones and itd have to be cold or have your jacket zipped up almost all the way.
i got a sessions syndicate jacket the other day and upon reading this thread i also found out i have this collar system. now all i need to get is some very small and load speakers.
So i just put Skullcandy in my Smith Holt helmet - controls on sessions co-op jacket forearm pumping pod to helmet is surely the most amazing music riding setup i have ever had
