These socks are knit with large loops of luxuriously soft 75% kid mohair and 25% nylon yarn. With unparalleled insulation and cushioning, they are the most comfortable, warm, durable socks that you will ever own. For the men’s med size and up, the grey socks are 10% thicker than the other colours, for that extra warmth.
Although, the large loops inside the socks are made with 75% kid mohair and 25% nylon, nylon is added to the outside of the socks to allow stretch and elasticity. This reduces the kid mohair content throughout the whole sock, but the loops you feel inside are still a 75% kid mohair / 25% nylon blend.
When including the outer layer of nylon, the total sock content is 70% kid mohair and 30% nylon.
