An icon of Scandinavian winters, the women's Kari Traa ROSE Long Sleeve Base Layer provides maximum warmth, perfect for building up on cold days. The Rose has a classy, feminine design and is made from superfine Merino wool with 4-way stretch. It's wonderfully soft on the skin, giving you natural breathability and odor-resistance. Thinner side panels under the arms and the high 4-button collar increase airflow during your high-output pursuits. The ROSE is a winter “must-have” layer.
