Designed as the ultimate foundation for your skin-to-environment layering system, the Black Diamond Solution 150 Baselayer ¾ 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. Designed at ¾ length, these bottoms pair well with ski or snowboard boots where fit is crucial.
