The Kari Traa Rose base layers provide maximum warmth and are perfect for building up on cold days. The Rose Pant is tight fitting with a classy, feminine design and is made from super fine, 1 percent Merino wool with 4-way stretch. It is wonderfully soft on the skin, breathable and naturally odor-resistant. Thinner side panels increase breathability and a strong elastic waistband keeps the pants snugly in place. A must have� base layer.
