Helly Hansen 75105 Lifa Base Layer Crewneck

The Helly Hansen 75105 Lifa Base Layer Crewneck is a lightweight long-sleeve base layer engineered for high-output activities in warm weather. It keeps you dry and comfortable when you’re pushing hard and sweating, making it ideal for runners, climbers, cyclists, and outdoor workers.

• Material & Weight: Main fabric is 100% Polypropylene at 125 g/m², delivering a breathable, quick-drying base layer that stays lightweight during activity.
• Moisture Management: Lifa® technology moves moisture away from the skin to maintain dryness as you train or work hard.
• Ideal Use: Built for high activity in warmer weather, perfect as a performance base layer under outerwear or on its own in milder conditions.
• Seam Design: No shoulder seams and no side seams, with flatlock seams to minimize chafing and maximize comfort during movement.
• Care & Durability: Easy-care instructions—machine wash at 40°C, avoid bleach, tumble drying, ironing, and dry cleaning to preserve performance over time.
• Technology Edge: Lifa® Stay Warm Technology helps maintain warmth where needed while still enabling excellent breathability during intense activity.

The base layer is designed to deliver practical, reliable performance without gimmicks. Its moisture-wicking action supports longer workout sessions, while the seamless construction reduces irritation during runs, climbs, or cycling. With quick-drying polypropylene and a streamlined crewneck fit, it’s a smart foundation piece that layers well under jackets or shells, keeping you comfortable from warm-up to cool-down. Regular care as recommended ensures longevity and sustained performance across seasons.
