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.

Material Specs
Merino Wool
Pure merino = endless comfort. Warm, ultra-soft, and naturally breathable, merino delivers on exceptional thermoregulation and moisture-wicking performance. We love its natural odour-resistant properties that keep you feeling fresh during any activity.
Balanced insulation and breathability
Our Warm layers offer an optimal balance between thermal insulation and active moisture management, neither function is sacrificed for the other. At the heart of the system, a Warm base layer is the right choice when cold protection and breathability are both required, from winter hiking and alpine skiing to cold-weather running. Best worn in a comfort range of -10°C to +5°C.
