Life jackets are rated in different classifications or types. When researching to buy your next life jacket, knowing what a life jacket is rated helps to understand how it will handle in an emergency situation. Type I life jackets are offshore jackets, with over 22 pounds of buoyancy, meant for survival conditions where rescue times may be slow. They will flip an unconscious person face up. Type II life jackets are meant for coastal applications, with over 15.5 pounds of buoyancy. Many will flip an unconscious boat face up. Type III life jackets are comfortable to wear when boating or fishing, but most will not flip an unconscious person face up in the water. Type IV life jackets are throwable flotation devices. Type V life jackets are often used in work setting on the water and must be worn while on the water.
