Abstract: A versatile safety device can serve as a personal flotation device, a rain- or splash-water repellent flotation jacket, a flotation vest with full and constant buoyancy, a multitemperature jacket or vest, a breathing raincoat, and a bullet/fragment-proof safety device, and has an inflatable chamber insert and an optional anti-ballistic insert in the collar. To fulfill all these tasks the device with jacket frame, sleeves and collar, all of which incorporate buoyant material with thermal insulation properties, comprises zippers in the sleeves with water protectors, leg-straps, vacant margins in the areas on the construction seams, and anti-ballistic portions attachable to the device.
