The Icebreaker Quantum IV Long Sleeve Zip Men is a wool-based outdoor layering piece designed to keep you comfortable when temperatures dip on the trail or around camp. Its straightforward design puts reliable warmth first, making it easy to wear on its own or under a shell.
Featuring a full-length zip and a stand-up collar, this long-sleeve top lets you adjust airflow as you move, while the natural wool fabric helps balance your body temperature. The zip front makes it simple to pull on or off over other layers, and wool’s innate breathability and resistance to odors help keep you feeling fresh during extended outings.
