The Icebreaker 200 Oasis leggings are an ideal base layer on cold days. Soft, breathable merino jersey provides cozy warmth under ski pants. At the same time, the leggings are perfect for morning runs in the transitional season or for hiking high in the mountains. Soft flat seams and a soft elasticated waistband prevent chafing. And because merino wool is odor-resistant, the leggings are ideal for multi-day adventures.
