Wool’s naturally high crimp means it can be easily spun into soft yarns to create highly efficient insulating fabrics. The physical property of textiles responsible for thermal insulation is closely linked to the fibres’ ability to trap air. Merino’s natural and permanent curly fibre makes it the ideal fibre for creating comfortable insulating fabrics.
However, while the mid-layer garment’s key function is to protect the wearer from the cold, the garment must also breathe so as to prevent the body from feeling clammy and humid. Merino’s ability to absorb the humidity created by the body and release it on the outside ensures the wearer experiences the best possible microclimate conditions.
Compared to other fabrics, Merino’s process to vapour transfer results in a more balanced or comfortable microclimate. Merino also stays fresher for longer. Its complex chemical structure locks the odour molecules within the fibre and only releases them on washing. It has a long-standing reputation for warmth and this can be attributed to its high natural bulk and elasticity which combines to give wool knitwear excellent insulating characteristics in a package that is light in weight, feels soft against the skin and has outstanding moisture buffering – a combination that cannot be duplicated by any other fibre.
