This invention relates to a firefighter's protective suit that combines anti-icing and warmth retention properties. It consists of a jacket and trousers. The jacket collar material, from the outside in, comprises an outer layer I, a waterproof and breathable layer I, a heat insulation layer I, an outer woven fabric layer I, and a warmth-retaining fabric layer I. The jacket hem material, from the outside in, comprises an outer layer II, a waterproof and breathable layer II, a heat insulation layer II, a comfort layer woven fabric III, and a warmth-retaining fabric layer II. The other parts of the jacket material, from the outside in, comprise an outer layer III, a waterproof and breathable layer III, a heat insulation layer III, and a comfort layer woven fabric V. The jacket cuffs are thickened ribbed cuffs. The trousers material, from the outside in, comprises an outer layer IV, a waterproof and breathable layer IV, a heat insulation layer IV, and a comfort layer woven fabric VII. This invention focuses on the warmth retention of the comfort layer and the anti-icing design of the outer layer of the firefighter's protective suit, achieving both warmth retention and anti-icing properties, ensuring the comfort of firefighters during movement and maintaining operational efficiency.
