Feel good, look good and stay warm and toasty in this cute Kari Traa Floke Long Sleeve shirt. It uses a blend of Merino wool with Lenzing Modal® fibers to create a soft and warm baselayer. This comfy top also manages moisture, breathes and is naturally odor-resistant. The Lenzing Modal® fibers are made using a low-energy production and are better for the environment. The jacquard knit patterns make it perfect for early morning long runs or sipping hot cocoa by the fire. The underarm panels mean that you can throw your hands up in surrender during your snowball fight without the garment riding up. Plus, it has flatlocked seams for a smooth finish.
