The Smartwool Intraknit Thermal Max is a men's merino wool base layer bottom built for serious cold. Its knit pairs insulating terry loops with mesh ventilation zones, so it traps heat where you need it and vents where you sweat. Knit-in reflective elements add visibility for low-light runs and dawn starts. Against synthetic thermal tights, it leans on merino's odor resistance and breathability, but it is a heavyweight piece meant for deep winter, not mild days.
