 Personal Flotation Devices - PFD's*

There are multiple types of PFD's available.  From Type I to Type V, which is the best for you.  The types most worn by Rescuers are Type III and Type V.   Type III vests are great for inshore, lake, and other calm water use.  Type V are special use and often have retrieval ring with a waist strap.  Take a look at this listing and the descriptions of the types.

Type I

Type I PFDs, are the most buoyant PFDs and suitable for all water conditions, including rough or isolated water where rescue may be delayed. Although bulky in comparison to Type II and III PFDs, Type I will turn most unconscious individuals to the face-up position. They range in sizes from adult to child.

Type II

Type II PFDs – or offshore buoyant vests – are designed and developed for environments where wearers find themselves in isolated or rough waters. Offshore PFDs offer high buoyancy, and are suitable for most water conditions.

Type III

Type III PFDs - or inshore buoyant vests - are specifically designed for activities where users can see the shore on calm or inland waters. Inshore PFDs offer comfort without compromising on user safety, technology, or design. They stand up to the test of speed. PWC-Rated vests are usually Type III.

These are designed to be thrown to a conscious person in the water. These are not designed to be worn. A few examples of a Type IV PFD are a buoyant cushion, a life ring, or a horseshoe buoy.

Type V -

These special use devices are to be worn for specific activities that will be described on the PFD’s label. To be effective, Type V PFDs must be used according to these specifications, and many must be worn at all times in order to qualify as a PFD. A Type V label will also list its performance as Type I, II, or III.  Most "GO" rescuer vests are Type V.
