I am trying to find out the brandname, make and availability of the
headgear that many of the football players from the University of
Michigan wear under their helmet.  It appears to be a nylon wrap of
some sort, and I have found that it is not a standard licensed product
through the NCAA.  I am interested in the specific maize and blue one
worn by these players, other color combinations are not desired.  A
complete answer will list the manaufacturer for me, as well as provide
where I can purchase the item, complete with a phone number or web
address.

Thanks!
