All about this product



A slim-fit midlayer that's ideal for technical mountain adventures, the Quantum III Long Sleeve Zip Jacket from Icebreaker helps regulate your body temperature and keep unpleasent odours at bay thanks to its 100% merino wool fibre construction. Odour resistant, quick drying and incredibly breathable, this Jacket is ideal for keeping you comfortable while enjoying activities such as running, skiing, hiking, climbing as well as being versatile and suitable for every day wear too. The Quantum III has underarm gussets and raglan sleeves for mobility, while the flatlock stitching and forward set side seams eliminate chafing. There are two zipped hand pockets and a zipped chest pocket to keep your personal items close to hand. The Quantum II features thumb loops to keep your sleeves in place and hands warm and the drop tail hem for added coverage. A lightweight fitted hood offers extra warmth and protection while being low bulk to be able to be worn under a helmet.

Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber that naturally resists odors, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
