The Solution 150 Baselayer ¾ Bottoms are the building blocks of success. These bottoms provide a superior foundation for your skin-to-environment layering system by utilizing NuYarn’s patented stretch merino wool technology, which is warmer and dries substantially faster than traditional merino wool fabrics. The Solution Baselayer ¾ bottoms also offer superior thermoregulation and moisture management, while remaining naturally anti-bacteria and odor resistant, keeping you fresh and dry while moving in the mountains.
