For most skiers, a 50/50 to 55/45 merino-to-synthetic ratio offers the best balance. This provides enough merino for effective odor resistance (3–4 days) while the synthetic component ensures durability and wicking speed. If you prioritize odor resistance for multi-day trips, lean toward 60% merino. If durability and fast drying matter more, a 45% merino blend works well. Always check for 2–5% elastane content for stretch.
