Altera Alpaca provided the basis for the first significant improvement in grassroots performance in two decades. Started in 2013, the goal is to create the best socks that are comfortable and durable. Altera Alpaca's alpaca socks have been tested by military standards to meet and exceed military standards. Alpaca fiber has legendary softness and unique thermal properties, so it is worth the effort to collect rare and time-consuming raw materials from their network of small domestic alpaca farmers. From a microscopic point of view, alpaca hair has a smooth outer surface, which is why it is as soft as silk. Alpaca has a unique hollow core, which can absorb moisture from the skin and provides up to 30% more insulation than Merino wool under hot or cold conditions. Total heat regulation even when wet!
