Shaped by millennia of evolution, Merino wool is a sustainable, natural material with unparalleled properties. Further increasing its innate insulating, anti-odour, and wicking abilities, our Merino + Carbon fabric with 37.5 Technology sees carbon particles embedded permanently within its fibres. Allowing our fabric to convert liquid into vapour up to ten times faster than conventional alternatives, this facility imparts superlative temperature-regulating qualities. A permanent feature of our ethically-sourced Merino, its benefits remain undiminished over the lifespan of the product.
