The Kari Traa Smekker Longsleeve is naturally breathable and odor-resistant. The ethically-sourced wool keeps you warm whether it’s wet or dry and feels great against your skin. Flatlock seams turn up the comfort level when you turn up the heat. Panels of Jacquard-knit patterns in different intensities create flattering lines. OEKO-TEX® 100 certification means that the main fabric poses no harm to human health.
