From the manufacturer:
A traditional and ever popular 4-ply yarn. A favorite for knitting socks, gloves and fine garments. The superwash wool allows for machine washing and drying for easy care and also wicks moisture away from the skin. Nylon content improves wearability and lends a super soft hand for comfort next to the skin. Many patterns are available, including books designed specifically for Kroy. Kroy's prints are spectacular with fast repeat colors that work up into subtle shade patterns.
