Woolx: natural-fiber picks
Not scored. This is a list of individual products, not a FabricTruth score.
Merino base layers and everyday wear. Every style uses merino, but only about a quarter are 100% merino; most add nylon and spandex, and a few are majority polyester.
What else Woolx sells
Almost everything Woolx sells is built around merino, but only about a quarter of the men’s styles we read are 100% merino. Most tees, hoodies and tops add 12–16% nylon and 3% spandex, the socks are roughly a third or more nylon, and a few pieces (the Mason and Watson layers, a balaclava and a beanie) are mostly polyester, nylon or acrylic.
- Most tees, hoodies and lightweight tops: 81–85% merino with 12–16% nylon and 3% spandex
- Socks: 56–66% merino with nylon and a little Lycra
- Mason and Watson layers: 55% polyester
- Merinoclava balaclava: 55% nylon; Baylor beanie: 50% acrylic
