Smartwool is pretty good at responsibly sourcing their materials and making good products, but the Merino 250 Baselayer with plant-based dye furthers that. As one of the heaviest baselayers they have, the Merino 250 will keep you mighty warm and comfy underneath a jacket as you brave serious winter weather. And, to top it off, its plant-based dye is an eco-conscious choice, so we can feel good about the clothes we wear.
