When it comes to standout thermals that perform as good as they look, Kari Traa continues to set the bar. What started with bold knit beanies designed by Olympic freestyle skier Kari Traa has evolved into a women-led brand known for colorful, confidence-boosting performance layers made to move, sweat, and ski hard.
Kari Traa is especially loved for its 100% merino wool base layers, prized for their ability to regulate body temperature in changing conditions. Merino wool is naturally moisture wicking, helping pull sweat away from the skin to keep you dry and comfortable on cold ski days or high-output adventures. It also offers natural antibacterial properties, making these thermals inherently odor resistant—perfect for long days, travel, or back-to-back wear.
Beyond merino, Kari Traa’s women’s ski apparel collection includes synthetic tops and bottoms and multiple weights of merino base layers, so you can mix and match the right system for any activity. True to the brand’s “for girls, by girls” philosophy, these thermals feature bold colors, playful patterns, and flattering fits you’ll almost hate to hide under your ski clothes (and might just show off on purpose). Originally introduced to the U.S. as a baselayer brand, Kari Traa has expanded into jackets, beanies, and the now-trending fuzzy fanny packs—bringing personality, performance, and Scandinavian style to every layer.
