Merino wool is the most popular choice for midweight base layers because the warmth level pairs well with merino's odor resistance for multi-day ski trips. Synthetics dry faster and are more durable, but they hold odor quickly at this warmth level. Merino-synthetic blends offer a practical compromise with good odor resistance and improved durability over pure merino.
