The technology
From merino to marine
We used to make knitwear from merino wool, until customers told us the same thing again and again: too delicate, too much hassle, and handwashing? No thank you.
So we went looking for a smarter alternative. Seawool® blends recycled plastic bottles with discarded oyster shells into a fabric that is machine washable, shrink-resistant, soft, temperature-regulating and odour-resistant. Same warmth, none of the babying.
