Helly Hansen LIFA Merino Midweight 1/2 Zip Base Layer Top Men's Black Size M

Most base layers force a choice: synthetic for moisture management or merino for warmth and odour control. The Helly Hansen LIFA Merino Midweight 1/2 Zip eliminates that compromise by fusing a hydrophobic polypropylene core with ZQ-certified merino wool in one seamless construction. The inner LIFA® fibres push sweat away from your skin, while the outer merino insulates, breathes, and resists odour—keeping you dry and comfortable from first chair to last run.

Highlights

• LIFA® Stay Warm Technology: polypropylene core wicks moisture outward; merino wool exterior regulates temperature and adds softness.
• Midweight fabric (approx. 215 g/m²) delivers balanced warmth for skiing, snowboarding, hiking, and trekking in cold conditions.
• 1/2 zip with stand-up collar allows quick ventilation and easy on/off; flatlock seams prevent chafing under layers.
• Naturally odour-resistant and breathable merino wool means fewer washes and all-day freshness.
• Regular fit with long sleeves and drop-tail hem for coverage and easy layering.

In daily use

Pull on the LIFA Merino Midweight as your first layer on a sub-zero ski day or a windy ridge hike. The zip lets you dump heat on the climb and seal it up for the descent. The fabric feels smooth against the skin—no itch, thanks to the fine merino fibres—and it dries quickly if you work up a sweat. Because it resists odours, you can wear it multiple days on a hut-to-hut tour without worry. Layer it under a shell or insulated jacket, or wear it solo during high-output efforts in milder cold.
