TheCOLMIC winter trousers are mainly made with a fabric composed of 95% cotton and 5% elastane in bonded twill. This combination of materials gives the trousers excellent elasticity thanks to the presence of elastane, which allows greater freedom of movement. The inside of the trousers is equipped with a fleece membrane. The fleece membrane is an insulating and thermal fabric that helps maintain body heat inside the trousers, making them suitable for cold winter days. This internal layer also acts as a barrier against the external cold, keeping the body warm and protecting it from low temperatures.
