Ready for technical mountain adventures like skiing, hiking and climbing, the Quantum III Long Sleeve Zip Hoodie is a slim-fit mid layer that helps regulate your body temperature during high-output days. Harnessing the natural benefits of its 100% merino wool fabric, the Quantum stretches with you, breathes efficiently and resists odours. Zippered hand and chest pockets secure your small essentials, while thumb loops keep your sleeves in place and your hands warm. Offset shoulder seams reduce rubbing when you're wearing a pack. 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.
