YOUR QUESTIONS ANSWERED
Why does alpaca perform better?
We spent years testing alpaca against cotton, wool and synthetics, and alpaca kept feet drier, more comfortable and free of odor. Its hollow-core fibers pull moisture away, regulate temperature in both heat and cold, and naturally resist odor, so a pair goes further between washes. It is softer than wool and more breathable than synthetics, which means all-day comfort without any itch.
How should I wash my Hollow Socks?
We recommend washing your Hollow Socks in cold water and hanging them to dry. Machine washing and drying have been tested as well, and showed no damage.
