A premium cold‑weather performance and recovery baselayer made from soft knitted merino wool and KYMIRA® infrared technology. Features cooling zones, adaptive stretch panels, quick-dry breathability and a body-hugging fit — perfect for athletes, hikers and winter wellness enthusiasts The KYMIRA® Infrared Merino Baselayer is our most advanced cold‑weather performance and recovery layer — now engineered with a heavier, soft knitted 3D Merino construction, expanded cooling ventilation zones, and ergonomic stretch panels for the perfect body‑hugging fit. Merino wool meets KYMIRA’s patented infrared technology to deliver elite‑level thermoregulation, circulation‑boosting benefits, and all‑day comfort. Infrared fibres increase warmth retention by up to 63% while improving microcirculation, oxygenation and tissue readiness through nitric‑oxide‑driven vasodilation. Merino wool wicks moisture rapidly, resists odour naturally, and maintains thermal balance across extreme conditions from −35ºC to +48ºC. Combined with its breathable, quick‑drying knit, flattering rib detail, and adaptive side and arm paneling, this is the most versatile baselayer for winter sport, outdoor exploration, and restorative recovery wear.
