AYAQ's RWS merino wool forms the most reliable foundation for an effective three-layer system. Sourced from free-range sheep farms and certified under the Responsible Wool Standard, it ensures animal welfare, traceability, and consistent quality. The fiber is then woven in Italy by a recognized eco-responsible specialist known for fine, durable technical knits. This approach produces garments that manage moisture better, stabilize body temperature, and maintain performance even when wet.
1. A natural fiber that regulates temperature
Merino acts like a natural microclimate: it traps warm air when cold but releases excess heat during exertion. Unlike conventional synthetic fibers, it continues to insulate even when damp, essential for ski touring, trail running, or mountaineering.
- BIAFO: lightweight merino for sustained efforts.
- MEFONNA: versatile merino for most seasons.
- SHIRWALI: warmer (~240 g) merino knit blended with Tencel for cool conditions.
- MOLVENO and ISEO: breathable alternatives for trail and high-intensity activities.
2. Superior moisture management
Merino absorbs water vapor before it condenses on the skin, preventing the common “cold damp” effect during climbs. On descents or breaks, the fiber limits sudden cooling, enhancing its suitability for sports with variable intensity.
This ability to perform even when wet is why Vincent Defrasne and Mike Horn use merino in their base layers during field tests: it provides thermal stability that other fibers struggle to match.
3. Natural feel and lasting comfort
AYAQ’s Italian-made merino knits offer fine softness that allows wearing the base layer directly on the skin. The fiber is naturally antibacterial, significantly reducing odors during extended use or multi-day outings.
4. A fiber aligned with AYAQ’s philosophy
RWS merino fully embodies AYAQ’s values: sustainable performance, low impact, European materials, and versatile apparel. Because it manages moisture, retains warmth, stays comfortable, and limits odors, it is the most reliable base for all outdoor activities. From ski touring to trail running, four-season hiking to mountaineering, RWS merino wool is a cornerstone of AYAQ’s layering system.
