The Merino 260 Quantum Long Sleeve Zip Hoodie is a slim-fit fleece mid layer that helps regulate your body temperature during technical, high-output pursuits like skiing, hiking or climbing. Harnessing the natural benefits of its 100% merino wool fabric, the Quantum stretches with you, breathes efficiently and resists odours. Backpack-compatible zippered hand and chest pockets secure your small essentials, while thumb loops keep your sleeves in place and your hands warm. Offset seams reduce friction 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 wool is an annually renewable fiber 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.
