Does viscose keep you warm in the winter?

Viscose is a semi-synthetic fiber made from regenerated cellulose, and while it has some insulating properties, it is not as warm as materials like wool or down. It can provide a degree of warmth, but it tends to retain moisture, which can make it feel cooler in cold, damp conditions. For winter wear, it's often best to layer viscose with warmer fabrics to ensure adequate insulation.
