Natural Insulator for All Season
The MERINOS WOOL line combines the natural thermal qualities of merinos wool with a lightweight, breathable design (164 g/m²). Perfect for cold winter days as a base layer or for the milder temperatures of transitional seasons, this line offers the right balance of warmth, comfort, and moisture control to support your performance in any condition.
Strategic Material Positioning for Optimal Performance
To deliver the signature comfort and functionality of SIXS, materials are positioned with precision: polypropylene sits closest to the skin for superior softness and moisture-wicking, while merinos wool forms the outer layer, providing lightweight insulation and thermal regulation. This design ensures the benefits of merinos wool without sacrificing softness or breathability.
Advanced Performance with Carbon Integration
Integrated carbon fibers elevate the MERINOS WOOL line with cutting-edge performance features: they assist in heat regulation, support microcirculation, and provide antistatic and bactericidal properties to keep bad odors at bay. The result is a garment that guarantees warmth, freshness, and superior comfort, making it ideal for dynamic activities across all seasons.
