Rowan Softyak DK transcends the seasons thanks to its blend of cotton, yak and nylon. It has a stunningly soft handle and is static resistant and anti-microbial, which means the fabric stays fresher for longer. While the ball bank indicates dk, I have knit Softyak at a gauge of 19 stitches/4" and been really happy with the fabric. Lovely to knit and to wear. The chainette construction makes it surprisingly light for a cotton rich double-knitting yarn and it's available in colors ranging from muted tones to rich jewel shades.
