Merino wool is one of the few fibers capable of adapting to diverse conditions: intense exertion, dry cold, temperature fluctuations, and long days in the mountains. Naturally antibacterial, thermoregulating, and soft, it is designed to last. However, like all natural materials, it requires special care. Proper maintenance of your merino garment preserves what makes it a reliable outdoor companion: its ability to manage moisture, retain warmth without overheating, and stay comfortable after hours of activity.
1. Why Care for Merino?
Merino’s scaly fiber structure allows it to absorb and release moisture, reduce odors, and maintain a stable temperature around the body. This fiber architecture is effective but sensitive to thermal shocks, harsh detergents, and aggressive spinning. Proper care ensures:
- Retention of fiber softness, essential for long-lasting comfort;
- Stability of the knit, which determines garment durability;
- Preservation of thermal properties: warmth in cold weather, coolness in mild conditions;
- Extended lifespan, even with intensive use.
Well-maintained merino ages slowly, retaining its technical qualities season after season.
2. Washing: Gentle and Gradual
To avoid stressing the fiber during initial washes, we recommend:
- First five washes in cold water, without heavy spinning;
- then a delicate cycle at max 30°C;
- washing inside out to reduce friction;
- using a wool-specific detergent free of enzymes and harsh agents.
Avoid machine spinning: excessive spin distorts the fiber and weakens the knit. Do not wring the garment, as this breaks the merino’s structure.
3. Drying: Preserve Shape and Fiber
Merino should dry naturally in the air. Tumble drying causes shrinkage and felting. We recommend:
- Flat drying for heavier items (thicker layers like SHIRWALI),
- or hanger drying for lighter t-shirts (BIAFO, MEFONNA, MOLVENO, TENNO, LÉVICO).
Avoid radiators and direct heat sources, which damage the protein structure of the fiber.
4. Between Washes: Merino’s Natural Strength
Merino has a rare property: it refreshes naturally when aired. After an outing, simply:
- Air the garment for a few hours,
- and let it rest so odors dissipate.
This avoids unnecessary washes, extending garment life and preserving fiber qualities.
Conclusion
Caring for merino is neither complicated nor time-consuming. It involves simple steps: gentle washing, limited spinning, natural drying, and regular airing. In return, merino retains what makes it valuable in the mountains and daily life: excellent moisture management, natural thermal regulation, and consistent comfort. Properly cared for, it becomes a dependable companion for long outdoor seasons.
