Originally created for fishermen going out in wet windy conditions at sea, a true fisherman's rib needs almost double the yarn of a plain knit jumper of the same size, making it extra warm when the weather closes in. This Hudson Aran is a 5gge chemical free British wool jumper, with natural water repellency and antibacterial properties. Sourced from a British Wool Accredited farm in Yorkshire - just 60 miles from our factory. Made in batches of only 200 pieces, get this special Aran knit while you can.
