Discover our merino wool sweater collection at icebreaker. Our sweatshirts are lightweight to keep you warm, dry and comfortable in all types of weather. Wear them on the mountain as part of our unique layering system for superior warmth, or in the office for an everyday casual look. Choose from a variety of styles including cardigans, half-zips and pullovers. No matter where you wear them, you’re sure to stay comfortable while looking stylish. Merino wool’s super-fine fibers are the perfect insulating material, trapping the heat between layers so you can stay warm without the added bulk or coarse nature of traditional wool. Be sure to check out our trousers, shorts and socks to complete your wardrobe.
