The 4F M166 thermoactive leggings are built for cold-weather training, using a quick-drying polyester-elastane blend that moves moisture away from the skin. The slim fit and flatlock seams reduce chafing during running, winter sports, or outdoor workouts, while the reflective 4F logo improves visibility in low light.

• Thermoactive base layer for autumn and winter activities
• Moisture-wicking 92% polyester, 8% elastane fabric
• Flatlock seams for comfort during movement
• Elastic waistband for a secure fit

These leggings work as a base layer under training pants or on their own during high-output sessions. The slim cut keeps them close to the body for effective thermal insulation, and the breathable fabric prevents overheating when intensity rises. Machine washable for easy care.
