From Kntting with Balls:
Historically, watchcaps were knit for (and by) fishermen using a lanolin-rich worsted-weight wool. The combination of tight stiches and a snug cuff doubled over the ears provided an impenetrable barrier against wind and salt from the sea. Today, every guy (fisherman or not) needs a warm hat to face the elements. This classic watchcap and ribbed scarf set is made from Cascade Pastaza’s combination of llama and wool, designed especially to provide warmnth. The fisherman’s rib gives way to a long-lasting elasticity, providing multiple layers to keep any guy warm on a blustery day.
