Helly Hansen Lifa Merino Midweight Crew in the colour Navy. Helly Hansen LIFA® Merino Midweight Crew Base Layer is a versatile base layer that adapts to various types of cold weather. The garment is constructed with a close-fitting two-layer solution in which a layer of 100% merino wool is combined with LIFA® Stay Warm Technology.

This combination delivers the natural, breathable warmth of merino wool while the LIFA® fibres efficiently transport moisture away from the body. The result is a comfortable base layer that keeps the body dry and warm during both low and high activity levels in cool conditions.
