N2N Ultra Skin Runner

According to the tag these tights are made from 83% nylon and 17% spandex, and the same applies to the C24 Ultra Runner tights I lent from my friend Chris in 2009 as well af the N2N Royal tights I received as a Christmas gift in 2010. Only my White Titan tights are sold as being in this 80/20 mix, and even for those it can't be confirmed at the moment.
