Cosy in soft, snug alpaca wool, cushioned in the foot for extra comfort, UphillSport 1 Pair Pispa Alpaca Wool Ultrasoft Socks deliver all the superb natural warmth that the wool is valued for. The knit of the socks is surprisingly lightweight and in a medium gauge thickness, soft and breathable to care for skin - even sensitive skin. Because alpaca is lanolin-free, it doesn’t provoke allergies like many wool products can. Alpaca is also naturally water-repellent and fire resistant. Extra warm, these high-rated thermal grade 5 socks are a high 80% alpaca-rich, designed and manufactured in Finland at UphillSport’s factory. They include polyamide to enhance durability and elastane for a stretch fit, but UphillSport recommend that because alpaca is a quite fragile wool, these luxury-feel socks are not for heavy duty active wear.
