Bamboo fibers are taken from the natural, fast-growing plant. Bamboo is softer and more breathable than cotton and has a natural sheen to the surface, so it almost feels like silk or cashmere. Bamboo is hypoallergenic, naturally microbial and very durable, making it a luxury choice for socks.
Nylon is a very strong, versatile, hard-wearing fiber. Socks made of nylon can be thin and silky or bulky and highly elastic. Nylon is often used with other fibers in blends to give added stretch or to improve durability.
Polyester and stretch polyester are two hydrophobic (water-repelling) fibers that are known for their durability and are extremely colorfast for vivid coloration.
Silk is a very smooth, soft and moisture-absorbing fiber. It boasts a high tensile strength and acts as a natural thermal retainer that does not conduct heat. It is woven from the cocoon material of special caterpillars.
