HELLY HANSEN Lifa Merino Midweight Pant Black

The LIFA® Merino Midweight Base Layer Pants for men by Helly Hansen are the ultimate base layer for staying warm and comfortable on the coldest days of the year. Designed for skiing, mountaineering, camping, or winter treks, these technical pants offer superior thermal protection without sacrificing breathability or freedom of movement.

Made with LIFA® Stay Warm technology, they combine an inner layer of LIFA® fibers — which wick moisture away from the skin — with an outer layer of 100% ZQ certified merino wool, known for its natural warmth, softness, and ability to regulate body temperature. This dual-layer (2-in-1) construction optimizes moisture management and insulation, providing constant thermal comfort during high-intensity activities or in extreme climates.

Their fitted design with flatlock seams enhances comfort and durability, while the non-itch fabric ensures a pleasant feel even in direct contact with the skin. Weighing 320g, these pants offer medium insulation (3/6), maximum breathability (6/6), and balanced lightness (4/6), ideal for wearing under ski pants or as a thermal layer for everyday winter use.

Additionally, the model features modern graphics that add a technical and contemporary touch to its functional design.
