Our alpaca day socks are a blend of 75% alpaca 25% nylon. Because of its soft texture, alpaca wool is often compared to cashmere. The fibre has the luster of silk, making it even more coveted.Alpaca is just as warm as sheep wool, yet it is a third of the weight. Containing no lanolin, alpaca fibre is naturally hypoallergenic. Additional performance characteristics include stretch & water repellency.We mix it with a very small amount of nylon, which makes it highly resilient against high levels of abrasion and friction.
