Minus the Challenge Jacket ($168) the new Challenge line has been uploaded this morning. The Challenge line is made of the new Silverescent Luon which has antibacterial and anti static qualities. The Challenge Tank and the Foundation Tank are both priced at $78. I think for that price I would like to see some pretty reflective design patterns on it..at least!
I think the idea is that you can do a 40 day Hot Yoga Challenge with these items and not have to wash your clothes between uses but I would probably be washing my clothes nightly anyways or alternating clothes.
