Portwest SK18 extreme cold weather sock with dual-layer Viafil insulation and 40% wool outer , Black/Grey

Built for cold-weather work:

The Portwest SK18 is a dual-layer performance sock designed for demanding cold-weather conditions in trades, warehousing, and outdoor work. The outer shell combines 40% wool, 40% acrylic, and 20% nylon to retain heat and manage odour, while the inner Viafil polyolefin layer provides insulation, moisture transfer, and anti-fungal protection. At 40 cm in height, these socks sit well up the leg for full coverage inside boots.

Comfort features that make a difference on long shifts:

A cushioned heel reduces friction between the foot and boot, lowering the risk of hot spots and blisters over extended wear. Knit gauge 9 construction gives the sock a firm, consistent shape that holds its position throughout the day rather than bunching or slipping down. The CE certification confirms the product meets European standards for protective clothing.

Moisture management and hygiene:

The Viafil inner layer draws moisture away from the skin and transfers it outward, keeping feet drier in cold and wet conditions. Antimicrobial and anti-odour properties built into the construction help maintain hygiene across long working days. The wool content in the outer shell contributes additional natural odour control alongside its thermal properties.
