Step 1
Type 1: These jackets are the most buoyant, providing 22 pounds of buoyancy in the adult sizes and 11 pounds of buoyancy in the children sizes. There is enough padding in the back of the jacket to ensure an unconscious swimmer will stay face up. These jackets are suitable for rough waters.

Step 2
Type 2: These life jackets are meant for inland or inshore waters. The United States Coast Guard describes them as Near-Shore Buoyant Vests and they are popular among recreation boaters. The adult size provides 15 ½ pounds of buoyancy and children sizes provide between 7 and 11 pounds.

Step 3
Type 3: These jackets have the same buoyancy parameters as Type 2 jackets but differ in their fit. They are designed for long-term wear and the vest fits closer to the body.
-
Step 4
Type 4: These are not life jackets but rather throwable devices that can be used for flotation. Examples include ring buoys, horseshoe buoys and cushion buoys.
-
Step 5
Type 5: These jackets are also called hybrid inflatables. The jackets provide some flotation on their own, and an inflatable compartment offers added buoyancy. When the compartment is inflated these jackets offer buoyancy comparable to that of a Type 2 or 3 jacket.
