All great systems have a solid foundation, and that’s why BD created the Solution 150 Baselayer Full-Length Bottoms. Designed as the ultimate foundation for your skin-to-environment layering system, the Solution 150 Baselayer Bottoms feature NuYarn’s innovative patented NuYarn stretch merino wool—a fabric that’s stronger, warmer, and dries faster than other merino wool fabrics by utilizing the technology of wrapping a nylon core with extra-fine merino fiber. This technology gives the Solution 150 Baselayer Bottoms superior thermoregulation and moisture management, plus they are naturally bacteria and odor resistant, making them the perfect next-to-skin layer for high-output activities in the mountains.
