A unique fibre from one of fabric partners, Octayarn has been developed to provide a modern lining fabric that insulates, wicks, and is exceptionally comfortable next to skin. We have pioneered its use since the fibre's development and are a close research and testing partner for new fabric developments in this area.

Octayarn is a multidentate (having many teeth, like a cog) fibre which boasts unrivalled surface area. This makes it superb at wicking moisture, decreasing drying times and ensuring you stay dry when working hard. The multidentate fibre shape increases bulk, and subsequently its warmth. The fibre is also extremely lightweight, offering the thickness of an 80 denier fibre but with only half the fibre weight. Octayarn fibres are hollow, increasing their air trapping and resultant warmth, and further reducing their weight. Octayarn is a unique fibre ideal for use in active insulation.
