Fit: A snug fit ensures better insulation and layering potential. Avoid loose-fitting options if you plan to wear them under jeans or dress pants.
Thermal Weight: Base layers come in different weights. Lightweight is great for mild conditions, midweight for everyday use, and heavyweight for extreme cold.
Performance Features: Look for moisture-wicking, odor control, and breathable fabrics if you’re wearing them during physical activity.
