The X-Bionic Merino leggings are a garment made of smart wool through the application of sophisticated technologies, such as the 3D Bionic Sphere system, so the wool cools and warms naturally when needed. The fine thread has a diameter of 18.5 micrometers and contains a natural elastic component.Features:- Compression level: medium- Insulation level: warm- Technical composition: 75% Merino wool, 23% Mythlan, 2% elastaneTechnology:- Aktiv-BundHighly elastic ends ensure a perfect fit without being too narrow.- Two-Step 3D-Bionic Sphere SystemThis technology ensures optimum grip and comfort as it provides different structures that transport moisture and heat.- ISO-PadAllows specific insulation in different parts of the body protecting from cold and freezing temperatures. This is how optimised ISO-Pads retain more body heat, which is necessary to ensure proper internal organ function and protection of the parts of the body that are most vulnerable to the cold.
