The Shell+™ Cotton Windbreaker Trucker Hat Logo Reflections combines icebreaker's Shell+ Cotton fabric for wind resistance in the front with 100% wool eyelet mesh back panels for enhanced thermoregulation. This lightweight, breathable hat is perfect for a hike, or any active day outside. The adjustable slider dials in the perfect fit. 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.
