The reference for natural-fibre thermal underwear
Natural fibres keep you warm by trapping still air in their structure.
Angora and merino wool do this better than any other staple fibre, and the properties that decide which wins in which cold are measurable, visible, and explained here end to end from the raw fleece to the finished garment.
Fibre & Heat is a new reference built around one question: why do angora and merino wool outperform everything else at trapping body heat, and how do you choose between them for the cold you are actually in? Every page on this site works from the fibre outward, through the garment, to the retail shelf.
