For ski balaclavas, a merino blend (typically 85–95% merino with nylon or elastane) is generally recommended over pure merino. The synthetic component improves stretch recovery, shape retention, and durability—addressing pure merino's tendency to lose shape when damp and develop holes at stress points. The small percentage of synthetic fiber doesn't significantly compromise merino's natural benefits. Pure merino is acceptable if you prefer 100% natural fibers and are willing to handle it more carefully.
