“Another sustainable, high-performance option is also one of the oldest: wool. Wool has several sustainable attributes: it is rapidly renewable, biodegradable, recyclable, and can be produced organically. There are also new wool traceability standards and animal welfare standards to track its production.
In terms of performance, wool is something of a miracle fabric. Highly durable, with inherent flame-resistant properties, it also has some natural water repellency. While not as slippery and oil-repellent as a perfluorinated finish, wool’s performance attributes are laudable without the added chemistry.”
