From technical days in the mountains to easy nights around the campfire, the icebreaker Quantum III Long Sleeve Zip keeps you comfortable. Cut from 100% merino wool, the midweight Quantum III helps regulate your body temperature when you’re on the move—keeping you cool in the heat and warm in the cold. Those same wool fibers also wick moisture and resist odor, so you smell fresh even after a long day of hiking. Zippered hand and chest pockets give you places to stash your stuff, and internal dump pockets give you additional storage for a pair of gloves or snacks. Designers also offset the shoulder seams to reduce friction when you’re carrying a pack. With a full front zipper that makes it easy to put on and take off, the icebreaker Quantum III Long Sleeve Zip delivers the performance you need when you’re heading outside.
