The Lurbel Manaslu Five are unisex thermal socks with H5 height (12–18 cm above the shoe), designed for trekking and extreme cold activities (–25 °C to –5 °C). They are made without perimeter seams and combine merino wool with Mulberry silk, a natural blend that enhances heat retention, breathability, and comfort. Their Bmax Merino Silk technology incorporates Regenactiv, wool, and silk to prevent blisters, manage moisture, and protect the skin. The Total Cushioning plantar structure provides a fully cushioned base for soft, comfortable steps. Additionally, the Antiodour Base Layer mesh offers a durable antibacterial and odor-resistant barrier. A technical, warm, and comfortable choice for mountain routes or winter expeditions.
