Empowered by the Laetts Merino Thermal System™, this heavy+, full-cushion fishing sock pairs a fine-gauge Merino blend with HygroHeat for maximum, self-sustaining warmth and active moisture control in frigid water. Full-foot terry with extended loops builds high loft to blunt cold-ground bite and ease long stands in waders, while a stable, resilient knit resists sag and compression when wet. Finished with reinforced heel/toe and odor resistance for all-day, static sessions on the creek—comfort that lasts when the water won’t.

Functions

  • HygroHeat™ Thermal Core

    Patented ceramic system reflects body heat using far-infrared (FIR) technology for self-sustaining warmth — without batteries or bulk.

  • Up to 8.8°C Warmer

    Lab-tested to retain significantly more warmth than standard Merino socks — for longer comfort in the cold.

  • Eco-Friendly Merino Blend

    Made with sustainably sourced Merino wool and performance yarns — soft on skin, lighter on the planet.

  • Moisture-Regulating Yarn

    Engineered fibers manage sweat and moisture to help keep your feet dry, even under pressure.

  • Natural Odor Control

    Merino’s natural antimicrobial properties help reduce odor — for fresher feet on long days.

    Advanced Technology for Unmatched Warmth & Comfort

    How HygroHeat™ Works

    •   Patented Thermal System

      HygroHeat™ is Laetts’ patented thermal technology that generates warmth through
      ceramic particles embedded directly into the yarns.

    • FIR-Emitting Ceramics & Reflective Design

      These particles emit far-infrared rays (FIR) to support circulation and thermal
      retention during activity. The visible white line on the sock is woven with
      reflective yarns that return body heat inward—no batteries, no external power.

    • Performance Warmth, Up to 8.8°C Warmer

      Lab-tested to retain heat better than leading ski sock brands, Laetts’
      HygroHeat™ keeps feet up to 8.8°C warmer.

    • Lightweight Comfort Without Bulk

      All the warmth—without heavy layers. Designed to provide extended comfort in
      ultralight constructions.
