Our ultimate running hat, combining icebreaker weather-resistant Shell+™ Cotton fabric with Cool-Lite™ eyelet mesh panels for breathability, the Shell+™ Cotton Windbreaker 5 Panel Cap was designed for fast-paced trail adventures and features reflective details. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fibre that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
