Abstract: A safety protection garment which enables a user to comfortably wear it during travel, and in which the garment can be rapidly prepared for an emergency for resisting impact forces or for providing buoyancy to keep the user afloat in water. The garment has an inner lining and outer shell which are joined together to form a chamber which contains a compressible layer. The compressible layer is formed of an elastic material which resiliently expands and contracts between memory and compressed shapes. A valve device enables the user to open and close air flow into the chamber. For normal wearing, the layer is in its compressed state with air substantially evacuated from the chamber and the valve closed. To prepare for an emergency, the valve is opened so that air enters the chamber sufficient to equalize the chamber pressure with atmospheric pressure. The layer then expands to its memory shape where it resiliently resists impact forces and also provide buoyancy to keep the user afloat in water.
