icebreaker offers the world's best merino wool layering system, designed to provide superior comfort and performance. Our men's base layers are crafted from superfine merino wool, meticulously sourced from our trusted growers in New Zealand. Merino wool is naturally breathable and excels at wicking moisture away from your skin, ensuring you remain comfortable throughout the day, no matter the activity or weather conditions. Our base layers, such as leggings and thermals, are engineered to offer warmth in even the most extreme cold. These layers can be worn under your winter clothes for added cozy comfort, providing a perfect balance of insulation and breathability. Merino wool regulates your body temperature in both heat and cold, making it an ideal choice for a variety of activities. Additionally, its natural odor-resistant properties ensure that you stay smelling fresh, even after a long day on the slopes or an intense workout at the gym. For versatile layering, pair our men's thermal underwear with men's shorts to create an adaptable system suitable for spring and autumn hiking and cycling adventures. Our base layers are designed to fit seamlessly under your outerwear, providing the flexibility to adjust to changing weather conditions without compromising on comfort.
