YOUR QUESTIONS ANSWERED
Why does alpaca perform better?
We spent years comparing alpaca with cotton, wool and synthetic blends, and alpaca kept winning: feet stay drier, more comfortable and free of odor. The hollow core of the fiber pulls moisture away, balances temperature in heat and in cold, and fights odor on its own, so a pair goes further between washes. It is softer than wool and breathes better than synthetics — all-day comfort with none of the itch.
How should I wash my Hollow Socks?
Our recommendation is a cold wash followed by hang drying. (For the record: in our tests, machine washing and tumble drying caused no damage.)
How do I know what size to get?
Use our sizing guide: Medium fits Men 6-9 (US) | Women 7-9.5 (US). Large fits Men 9.5-12 (US) | Women 10-13 (US). Extra Large fits Men 12.5-15 (US).
