✨ Why You'll Love It
-
🐑 Ultra-Fine 16.5μm Merino Wool
100% Merino wool construction (excluding stitching) — one of the finest grades available, delivering exceptional softness against bare skin with zero itch, even during extended wear.
-
🌡️ Superior Thermal Regulation
Merino's natural crimp structure creates insulating air pockets that lock in warmth during cold conditions while still breathing efficiently during high-output activity — ideal for alpine environments, ski touring, and cold-weather expeditions.
-
💧 Moisture-Wicking & Odour-Resistant
Naturally antimicrobial fibres actively wick sweat away from your skin and resist odour buildup — stay fresh and dry through multi-day backcountry trips without frequent washing.
-
🔒 Stand-Up Collar Protection
The structured stand collar seals in warmth around your neck and shields against wind and cold air — eliminating the need for a separate neck gaiter in moderate conditions.
-
🌍 Versatile Layering Performance
Sits flush against the body for seamless layering under mid-layers and shells without bunching or restricting movement — the foundation of any serious cold-weather layering system.
