Merino wool is an incredible fibre. The properties are almost too crazy to believe; anti-microbial, water-repellant, insulating-yet-breathable, the list goes on.

The long-term wear issue of merino has been overcome by weaving in a similarly impressive man-made yarn called 37.5® polyester which helps to keep your body temp at 37.5ºC whilst maintaining the microclimate next to your skin at a humidity of 37.5%. This technology is permanently embedded into the fabric and it'll last the lifetime of the garment since it's not a chemical finish.

Unlike other wool garments this can be machine washed. A godsend given how much you'll likely be wearing it.
