The Solution 150 Merino Base Crew is a women's technical base layer designed by the brand Black Diamond to be worn as a first layer during your outdoor activities in cold weather, such as snowshoeing, trekking, or during your ski days. Indeed, this base layer is the first pillar of the three-layer system and provides effective thermal insulation thanks to the natural properties of merino wool, all in an ultra-thin, stretchy layer. The Solution 150 Merino Base Crew also incorporates NuYarn technology into this merino wool, allowing for faster drying than traditional merino wools and superior thermal comfort. Additionally, merino wool offers odor neutralization and optimal moisture wicking, providing you with total comfort even during your most intense outdoor sports. Finally, the flat seams and thumbholes of the Solution 150 Merino Base Crew complete its status as a comprehensive technical base layer that you won't want to take off!
