Designed for long work hours, our socks are made with unbelievably soft and durable alpaca fibers. Providing superior comfort and cushion, reducing fatigue, and helping you stay on your feet longer.

Alpaca fibers have a hollow core that helps regulate temperature, making Hollow Socks so breathable that they can be worn year-round - keeping your feet cool in the heat or warm in the cold.

Unlike sheep’s wool, alpaca fibers contain keratin, a protein that provides antifungal and antimicrobial properties. This helps keep your socks stink-free and allows you to go much longer between washes than traditional wool socks.

Alpaca fleece can absorb up to 30% of its dry weight in moisture and still feel dry to the touch. As it absorbs, it quickly moves moisture away from your skin to the surface of the fabric where it then evaporates - making them a perfect match for sweat, rain, mud, or whatever else the day brings.

Hollow Socks are proudly made in the USA utilizing some of the most modern manufacturing techniques available. Tested on job sites across the country, Hollow Crew Socks are bound to become your new everyday pair.
