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, while retaining shape with a natural bounce. 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.

Great top

So Ive been waiting like Pablo for about a year for the Henning LX to come back in stock to no avail. Saw this and loving merino decided to get one in oat. Such a good top, comfortable, warm and looks great. Far better than my Fjallraven merino if you want an idea of the quality. Straight away ordered another in Blue, with the 30% off code that came with the first one it was a no Brainer. Jottnar definetly my favourite outdoor brand. The quality is unsurpassed.

Happy hiker

I’m really pleased with my Marino Heimdall base layer. Really soft and comfortable piece of kit which I’ve worn in the fells. Great fit, not too tight and feels great next to the skin.

Just what you would expect...

Another fine piece from the Jottnar team ... lightweight yet very warm when paired with the right outer shell.

Works well in Alaska skiing

Wore this whilst skiing in Alaska. Very warm, very comfortable, great range of movement, and no smell even after multiple days usage.
