Types of PFDs

There are many different types of PFDs (Personal Flotation Devices). Here is a list describing each type and there intended use.

Type I -	Provides the most buoyancy. It is effective for all waters, especially open, rough or remote waters where rescue may be delayed. It is designed to turn most unconscious wearers in the water to a face-up position.
Type II -	Intended for calm, inland water or where there is a good chance of quick rescue. Inherent buoyant PFDs of this type will turn some unconscious wearers to a face-up position in the water, but the turning is not as pronounced as a Type I. This type of inflatable turns as well as a Type I foam PFD.
Type III -	Good for conscious users in calm, inland water, or where there is a good chance of quick rescue. It is designed so wearers can place themselves in a face-up position in the water. The wearer may have to tilt their head back to avoid turning face-down in the water. The Type III foam vest has the same minimum buoyancy as a Type II PFD. It comes in many styles, colors, and sizes and is generally the most comfortable type for continuous wear. Float coats, fishing vests, and vests designed with features suitable for various sports activities are examples of this type PFD. This type inflatable turns as well as a Type II foam PFD.
Type IV -	Intended for calm, inland water with heavy boat traffic, where help is always present. It is designed to be thrown to a person in the water and grasped and held by the user until rescued — It is not designed to be worn. Type IV devices include buoyant cushions, ring buoys, and horseshoe buoys. There are no inflatable Type IV devices.
Type V -	Intended for specific activities and may be carried instead of another PFD only if used according to the approval condition(s) on its label. A Type V PFD provides performance of either a Type I, II, or III PFD (as marked on its label). If the label says the PFD is "approved only when worn" the PFD must be worn, except for persons in enclosed spaces and used in accordance with the approval label, to meet carriage requirements. Some Type V devices provide significant hypothermia protection. Varieties include deck suits, work vests, and board sailing vests.
Type III/V -	Multi-Purpose Commercial Vests.

Well that's a bit to take in. Thank you to NRS for shortening the descriptions quite a bit. (Yeah, I cheated a little.)

And now for some examples:
Type I

Type II

Type III

Type IV

Type V

One thing to remember, within each type, there are different styles, makers, colors, and fits.

I've used the Type V for quite a few years now, only because I've a lot of years on rivers and I have received some training in swift water rescue.  I highly recommend that beginners start with the Type III. I know I did.

I want to end this by saying,
It is important that when choosing a PFD, to choose one that is right for your situation. So take some time and consider the options.


Talk to you later,
