Icebreaker Merino® designs apparel for everything from outdoor adventures to everyday living—from underwear, socks and accessories, to fitness apparel, outerwear and sportswear. Icebreaker uses only the finest New Zealand Merino wool fiber: soft, silky, breathable and totally insulating. Since it doesn't hold odor, Icebreaker Merino can be worn for days in a row. And since it’s machine washable, it’s easier to care for than cashmere. It’s the best insulation nature has to offer, with smart design to maximize performance in any weather.
