Your Questions Answered
Why does alpaca perform better?
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.
