Explore our collaboration with artist Justin Brice Guariglia. The limited-edition range of beautiful base layers, T-shirts and jackets is made with soft merino fibers that breathe naturally next to your skin. The topography of our changing planet is featured on the fabrics to embody the conversation around climate change action. Our signature icebreaker merino wool is a superfine, annually renewable fiber grown in the rugged Southern Alps of New Zealand. It faces the ultimate field test out in nature and has adapted to keep the merino sheep warm during harsh winters and cool in scorching summers. Durable for everyday wear, lightweight and soft against your skin, merino wool is nature’s performance fiber, wicking away moisture and regulating your body temperature to keep you in your comfort zone, whatever the conditions.
