After years of testing against cotton, wool, and synthetics, alpaca stood out for keeping feet dry, comfortable, and odor-free. Its hollow-core fibers wick moisture, regulate temperature in both heat and cold, and naturally resist odor, so you can wear them longer with fewer washes. Softer than wool and more breathable than synthetics, alpaca delivers all-day comfort without the itch.
