Alpha Wool Jacket FAQs

  • Pertex® Quantum Air fabric delivers weather resistance and breathability on the exterior. PFC-free DWR etc.

  • Polartec® Alpha™ Direct insulation blended with wool lines the interior, keeping natural fibers next to your skin. Originally developed for U.S. Special Forces, Alpha insulation keeps you comfortable through both movement and rest. And with wool blended in, it’s warmer and more odor resistant.
