Helly Hansen 75209 Women's Lifa Base Layer Merino Crewneck

The Helly Hansen 75209 Women’s Lifa Base Layer Merino Crewneck is a high-performance first layer designed for women who stay active in cold conditions. By weaving Lifa® fibers with merino wool, it delivers reliable warmth and efficient moisture management in a single, comfortable piece.

• Fabric composition: Main fabric blends 57% Merino wool and 43% Polypropylene at 215 g/m² for warmth, durability, and moisture transport.
• Technology: Lifa® Stay Warm technology paired with Lifa Merino fibers to help keep you warm while moving and to move moisture away from the skin.
• Seam construction: No shoulder seams and no side seams to minimize irritation; flatlock seams for smooth, comfortable movement.
• Fit: Tailored for a true female fit that sits close to the body without restricting activity.
• Care instructions: Machine wash at 40°C on a very gentle cycle; do not bleach, tumble dry, iron, or dry clean.

This base layer helps regulate body temperature and wick sweat during runs, hikes, ski sessions, or any cold-weather training. The combination of merino warmth and Lifa® moisture transport keeps you dry and comfortable, even as you push through prolonged activity. The seamless design and flatlock stitching reduce chafing, making it an ideal layer under jackets or shells. Optimized for women, it accommodates movement across a range of activities—from alpine slopes to brisk commutes—while preserving a lightweight, breathable feel.
