Lorna's Laces Sportmate is a sport-weight yarn with built-in climate control. It's made from 30% Outlast, a fiber technology that interacts with the body's microclimate to moderate temperature from being too hot or too cold. Sportmate is available in a range of beautiful hand-painted colorways. Because there are no dye lots, colors may vary slightly. Find out more about knitting with hand-dyed yarns.
