Buying advice

When choosing a thermal top, consider your primary use: for general cold-weather layering, lightweight synthetics like 32 Degrees offer great value. For high-output activities, moisture-wicking options like Under Armour or REI Co-op are better. Merino wool (e.g., Merino.tech) is excellent for odor resistance and comfort but pricier. Pay attention to fit: some brands run small, so check reviews. Look for features like flatlock seams to prevent chafing and thumbholes for extra coverage.
