Helly Hansen 79643 Chelsea Evolution Winter Insulated Sock

Designed for cold-weather activity, the Chelsea Evolution Winter Insulated Sock delivers warmth, dryness, and everyday durability for outdoor enthusiasts and winter commuters alike.

• Material blend: Main fabric combines 39% polyamide, 37% polypropylene, 22% wool, and 2% elastane to balance durability, warmth, and stretch for a comfortable, snug fit.
• Lifa® fibers in heel & toe: Reinforced in the high-wear zones to boost durability and transport moisture away from the skin, helping keep feet dry in cold conditions.
• Mesh ventilation: Built-in breathability reduces overheating during activity, improving overall comfort during long treks or rapid climbs.
• Ankle flex design: A flexible ankle area supports natural movement inside boots or shoes, reducing constriction and enhancing all-day wearability.
• Winter insulation: Engineered to maintain warmth without excessive bulk, making these socks suitable for icy mornings and snowy trails.
• Care instructions: Machine wash cold (30°C) on a very gentle cycle; avoid bleach, tumble drying, ironing, or dry cleaning to preserve fiber performance.

The combination of Lifa® moisture management, wool warmth, and a durable polyamide- polypropylene base helps prevent cold, damp feet and blisters on strenuous winter days. The heel and toe reinforcement extends sock life where wear is most intense, while mesh ventilation keeps feet comfortable during sustained activity. Ideal for hiking, backcountry skiing, winter commuting, or everyday use in chilly weather, this sock offers a practical, reliable solution for staying warm and dry. Easy care means it fits seamlessly into busy outdoor lifestyles and travel routines.
