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.
