Lang Jawoll Superwash is a sock wool classic! This fingering-weight yarn is spun with wool from Corriedale sheep (sourced in Chilean Patagonia) with a touch of polyamide. The average thickness of the wool is only 25 microns, which means Jawoll Superwash is super soft. It’s also highly resistant to pilling—an excellent quality for knitting projects that undergo a bit of friction. And with every skein of Jawoll Superwash, Lang includes a small spool of reinforcement yarn—to strengthen your socks’ heels and toes even further. Jawoll is also wonderful for baby/toddler knits and for men's knitwear.
