It depends on your priorities. Merino wool offers superior natural odor resistance (great for multi-day trips), excellent temperature regulation, and a soft feel against skin, but it's more expensive and less durable. Synthetic options (nylon-spandex blends, polypropylene) offer better durability, faster drying, and typically lower cost, but require antimicrobial treatments for odor control that degrade over time. For week-long ski trips, merino is worth the investment. For weekend warriors who wash between uses, synthetics offer better value.
