Functions

  • HygroHeat™ Thermal Core

    Patented ceramic technology reflects body heat using far-infrared (FIR) energy to support self-sustaining warmth without batteries or bulk.

  • Moisture-Regulating Merino Comfort

    Merino fibers naturally manage moisture and odor while engineered fibers help maintain comfort during extended activity.

  • Ultralight Thermal Build

    Engineered for maximum warmth-to-weight performance, this lightweight construction maintains a thin, responsive profile for precise fit inside performance boots.

    ADVANCED MOISTURE-RESPONSIVE THERMAL TECHNOLOGY

    How HygroHeat™ Works

    HygroHeat™ uses ceramic-enhanced fibers engineered to generate and retain warmth through moisture-responsive technology. By converting natural body moisture into heat energy and reflecting far-infrared (FIR) radiation, HygroHeat™ helps maintain comfortable warmth without batteries, bulky layers, or external power. The result is lightweight thermal performance designed to keep feet comfortable across changing activity levels and conditions.
