Alpaca Performance

  • Outperforms Merino

    The hollow core of natural alpaca fiber insulates up to 30% better than merino wool in any weather even when wet. It is also naturally odor resistant and itch-free.

  • Thermal Regulation

    The natural wicking properties of alpaca fibers help to regulate temperature in any weather. It insulates like wool in the cold and provides an evaporative cooling effect like cotton in hot weather.

  • Extreme Comfort

    The hollow nature of alpaca fibers allow them to continue to provide insulating warmth even while wet. The fibers also continue to wick away the moisture as the fibers dry out.
