Merino Performance, Quarter-Zip Versatility — Built for the Long Haul.

The Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip is a cold-weather essential engineered from 100% Merino wool for natural temperature regulation, moisture management, and odor resistance.

This Navy colorway pairs cleanly with any shell or mid-layer in your kit.
