This yarn is a new kind of Supersock, one with nylon!  It is composed of 80% superwash merino/ 20% nylon and offers the softness of supersock without the need for a high twist as the nylon provides longevity.  Although it is designed for socks, the yarn is so soft that many knitters prefer it for baby blankets, and hat and scarf sets.  The yardage can't be beat, there is plenty for a pair of socks.
