The NuYarn fabric technology utilised in the Winter Base Layer is comprised of a nylon core wrapped with merino wool. This composition has been explicitly chosen because it not only improves upon the natural properties of woollen garments but eradicates inevitable wear that comes with traditional wool. The Winter Base Layer is demonstrably warmer, comfier, lighter, tougher and longer lasting than traditional woollen base layers. It even dries five times faster than its competitors.
