The Rundown
Made with Janus AirWool®—a lofty, 230-gram brushed merino developed exclusively for us by Norwegian wool producer Janus Wool—this lightweight half-zip delivers exceptional warmth and breathability. Drawing on more than 130 years of wool expertise, AirWool is created using a specialised brushing process that traps an extra layer of air between the wool fibres. The result? A light, airy fabric structure that insulates without added weight, beautifully regulating body temperature. This mid layer is odour-resistant by nature, so it stays fresh longer between washes. Ideal for layering up on the coldest days or wearing solo in milder weather. Finished in our own European facility. A premium mid layer made from the finest merino fibres.
