B_WOOL® is a sustainable textile innovation developed by ecmo™. This material represents the brand's commitment to sustainability and technical excellence. This fiber is made from very high-quality virgin wool, spun in Italy and then knitted in Brittany in a tight 7 or 8 gauge knit. Thanks to an innovative treatment, this exceptional fiber is endowed with water-repellent properties: it protects against wind, salt, and humidity, while preserving incomparable softness and elegance.
