Helly Hansen LIFA Merino Midweight Crew Base Layer Top - Men's Dark Blue Size L

The Helly Hansen LIFA Merino Midweight Crew sets itself apart by combining the moisture-wicking power of LIFA® polypropylene with the natural warmth and odor resistance of ZQ-certified merino wool. This two-layer construction moves sweat away from your skin while trapping heat, making it a versatile base layer for cold-weather pursuits where staying dry is just as important as staying warm.

Highlights

• LIFA® Merino fabric: 57% merino wool, 43% polypropylene for optimal moisture management and insulation
• Midweight warmth (approx. 215 g/m²) ideal for high-output activities in cold conditions
• Flatlock seams prevent chafing and enhance durability during dynamic movement
• Naturally odor-resistant merino wool keeps you fresh on multi-day adventures
• Regular fit with crew neck and long sleeves for easy layering under midlayers or shells

In daily use

On the trail, ski slope, or winter commute, this crew delivers reliable performance. The polypropylene inner layer rapidly transfers perspiration to the merino outer layer, where it evaporates, leaving you dry and comfortable even during intense exertion. Merino wool regulates temperature across a wide range, so you stay warm when temperatures drop and cool when the pace picks up. The flatlock seams lie smooth against the skin, eliminating irritation under pack straps or harnesses. With its dark blue color and clean design, it transitions seamlessly from technical base layer to casual winter wear.
