Men's LIFA® Merino Midweight Half-Zip Base Layer

The men's LIFA® Merino Midweight Half-Zip is a 2-layer cold-weather base layer combining a soft 100% merino-wool exterior with moisture-managing LIFA® fibers against the skin. It delivers natural warmth and odor control with faster moisture movement for skiing, hiking, mountaineering, and winter travel.

The fitted half-zip design adds ventilation and a double-layer collar, while flatlock seams reduce friction. Helly Hansen rates breathability 6/6, insulation 3/6, and lightness 4/6.
