The stretch material makes it comfortable to use in any situation. Water repellent, waterproof (water pressure resistance 10,000mm), moisture permeable (5,000g/㎡・24h) material. Y-WARM, a sheet with excellent heat insulation and moisture permeability, is used for the body and hood. Y-Warm is a material with lower thermal conductivity than the "aerogel" used in spacesuits. Composed of micron-sized particles with extremely low thermal conductivity, it forms a polymer barrier that prevents the transfer of thermal energy, retains heat without escaping, and effectively insulates and retains heat by preventing cold air from entering.
