Men's Extrafine Merino Baselayer

Crafted from one of the finest merino yarns, Heimdall is a flatlock seamed technical baselayer designed for exceptional warmth, breathability, and performance in challenging conditions. Ideal for inbounds skiing, off-piste adventures, mountaineering, and expedition use, the super-soft durable merino delivers all-day comfort and regulating warmth, even when wet. Naturally odour and crease-resistant, as well as antimicrobial, you’ll stay fresher for longer even on multi-day trips.

Our extrafine merino yarns use fibres of 19.5 microns or under, making them extremely fine. Renowned for an exquisitely soft and silky feel, yet naturally retaining shape. Due to Heimdall's fully-fashioned build, the flatlock seams lie smoother against the skin, giving optimum comfort, freedom of movement and a luxurious, polished look. Perforated side and underarm panels enhance airflow, and the double layered rib collar gives wind-blocking warmth with natural stretch. Finished with a reverse coil, auto-lock half-zip for better longevity and ease of use.

Extremely time-intensive to craft and a zero-waste benefit, you’ll immediately appreciate the finer detailing of this luxury baselayer against your skin. Given extrafine merino’s outstanding temperature control, wear as a breathable standalone in warmer weather, or get exceptional warmth when layering for cold adventures.
