Should I choose pure merino or a merino-synthetic blend?

For most skiers, a merino-synthetic blend (typically 80/20 to 60/40) is the practical choice. Blends retain 60–80% of merino's odor resistance while offering significantly better durability, faster drying, and better shape retention. Pure merino makes sense if odor resistance is your absolute top priority (e.g., extended backcountry trips) and you're willing to handle the garment carefully. If you're hard on gear, ski very frequently, or prefer low-maintenance care, blends are the smarter investment.
