The Desoli Headband is a slim-fitting performance headband knit from 17.5-micron super fine merino wool, offering natural temperature regulation whether conditions are cold or warm. At just 20 grams and constructed from a 150 g/m² fabric, it sits comfortably under a ski or climbing helmet without adding bulk. Merino wool's inherent properties mean it resists odor, retains warmth even when wet, and moves moisture away from the skin during high-output activity. The wool is mulesing-free and sourced from traceable Australian farms, and the headband is fully recyclable through the brand's in-store take-back program.
