Featuring UPF 40+ sun protection, and icebreaker water repellent Shell+™ Cotton fabric, the Shell+™ Cotton Windbreaker Wide-Brim Hat is a comfortable and protective adventure hat. A Cool-Lite™ eyelet mesh interior headband helps wick moisture on hot, sunny days, and an adjustable cotton chin strap keeps the hat secure on windy days. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool 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.
