Smartwool Classic Thermal Merino 1/4 Zip - Women's Base Layer

The base layer you wear under everything, and the one that makes the difference. Smartwool's Classic Thermal Merino is knit in 100% merino wool interlock at 250 g/m²: warm, breathable, and naturally odor-resistant even through a full day under a suit. The slim fit follows body contours without extra fabric bunching under your layers.

Flatlock seam construction eliminates pressure points against skin. Raglan sleeves remove shoulder seams that bind under a jacket. The quarter-zip lets you vent quickly without pulling off a layer.

SPORTS DRC EXPERT TIP
The 250 g/m² weight puts this in the thermal category, the right call as a base for snowmobiling, skiing, or any high-output winter activity. Wear it directly against skin so the merino wool can manage moisture effectively. Skip the synthetic underlayer.
