Our alpaca socks provide unbeatable insulation for your feet, keeping them warm and comfortable even on the coldest days. When it's hot the alpaca fibers breathe keeping you cool when it counts.

Alpaca fleece is naturally moisture-wicking, quickly absorbing and moving moisture away from your skin keeping your feet, socks, and boots dry all day, in any condition.

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.

Hollow Socks are built to last and are proudly made in the USA, with premium alpaca fibers that have a tensile strength of up to 50N/ktex, which is 25-30% stronger than Merino wool. Tested on job sites across the country Hollow Boot Socks are bound to become your new go-to pair.

Ready to give Hollow a try? We’re confident that you’ll never want to set out on another job without them. If for some reason you find that alpaca socks aren’t right for you, we offer a 30-day money-back guarantee, no questions asked. So what do you have to lose?

"So far I've only used these in hot weather. I'm impressed that my feet don't get hot and are well cushioned. They don't feel bulky in my boots. I can't wait to experience them in the winter."
