Warmer. Lighter. Stronger. Icebreaker's RealFleece has recycled Merino fiber wrapped around a nylon core, then brushed to maximize warmth and softness. With a hint of lycra, the Men's Sierra Long Sleeve Zip fits like a charm and is built for performance and keeps out the cold when you're hiking, skiing or sightseeing.
Nature created Icebreaker merino wool as protection against the scorching summers and freezing winters of New Zealand’s rugged Southern Alps mountain range. The merino is one of the world’s most ancient and toughest breeds of sheep.
Icebreaker has pioneered the use of merino wool in the wilderness since 1994, and have now fused nature and technology to create merino layers for the outdoors, for performance sports, and for the city. Icebreaker merino garments are soft and non-itch, warm in the cold and cool in the heat, they breathe to prevent clamminess, and have a miraculous ability to warn off stinkiness.
