What's in this duo 1 pair — Alpaca Crew Sock, Black 1 pair — Alpaca Crew Sock, Grey Save £5 versus buying the two colours separately (£46.00 individually, £41.00 as a duo). Why alpaca? Naturally temperature-regulating — hollow-core fibres trap warmth in the cold and release heat when it's warm, so feet never overheat. Moisture-wicking — pulls sweat away from the skin to keep feet dry and help prevent blisters on long days. Odour-resistant — naturally antimicrobial, so socks stay fresh even after hours of wear. Hypoallergenic & itch-free — lanolin-free alpaca is kind to sensitive skin, with none of the itch of sheep's wool. Lightweight warmth — serious insulation without the bulk, fitting comfortably in boots, trainers, and everyday shoes. Curious why alpaca outperforms standard wool?
