Treated making it UV resistant, wear-resistant and yet still able to give more than one hundred percent elongation. With our shockcord, rubber degradation is not an issue to worry about. 
 
It comes in 10-metre hanks. If you're ordering multiples, we will send as one continuous length (50-metres max).
