Empowered by the Laetts Merino Thermal System™, this Heavyweight Outdoor sock with Full Cushion construction uses a refined dual-yarn build that pairs dedicated HygroHeat™ alongside fine-gauge Merino wool for balanced, self-sustaining warmth and enhanced moisture stability in cold, demanding conditions. Dense, full-foot cushioning helps blunt cold-ground conduction and relieve pressure in boots and waders, while a stable, resilient knit maintains structure and comfort—even when wet.

Designed for extended wear in cold environments, reinforced heel and toe zones enhance durability, while natural odor resistance keeps feet comfortable through long hours outdoors. Ideal for fishing, hunting, and cold-weather work, this is Laetts’ most refined Heavyweight construction, offering premium warmth, comfort, and feel for all-day use.

Odor-Free Comfort

  • 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.

  • Natural Odor Control

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

  • Moisture-Regulating

    Engineered fibers actively manage sweat and moisture to keep feet dry and comfortable—even under sustained pressure.

  • Adaptive Fit Support

    Comfortable for skiers with reduced strength, post-surgery needs, or limited dexterity — boot entry takes less effort.

    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 sock structure.

    • 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 maintain comfort across changing activity levels while preserving fit precision and mobility.
