Born in the Southern Alps of New Zealand, the merino sheep has a light, super fine, highly breathable coat that keeps him cool in the scorching summer heat. When winter sets in, he grows an extra layer of wool over his base coat so he can roam through ice and snow in warmth and comfort. We've taken the merino's wool and created a system of lightweight layers to give you the same freedom to explore your environment in any condition. Wear a next-to-skin layer in warmer weather, then layer up for insulation in the cold. Created by Nature. Adapted by Icebreaker.
