icebreaker has the world’s best merino wool layering system. Our men’s base layers are made with superfine merino wool, sourced from our growers in New Zealand. Merino wool clothing is naturally breathable and wicks moisture from your skin, so you can stay feeling comfortable all day. Our merino leggings and thermals for men can be worn for warmth in even the most extreme cold, or under your winter clothes for cozy comfort. Merino regulates your body temperature in both heat and cold, and is naturally odor-resistant, so you can stay smelling fresh after a long day in the mountains or a hard workout at the gym. Pair our men's thermal underwear with men’s shorts
to create a versatile layering system for spring and autumn hiking and cycling adventures. Or if you're looking for something more casual, browse our collection of men’s t-shirts
