Useful Tips on Selecting the Right Type of Life Jackets

1. Determine the Water Environment

Open and Rough Waters

  • Type I PFDs (Offshore Life Jackets): These provide the highest buoyancy (at least 22 pounds for adults) and are designed to keep the wearer’s head above water even if unconscious. Ideal for open, rough, or remote waters where rescue may take longer.

Calm, Inland Waters

  • Type II PFDs (Near-Shore Buoyant Vests): River life jackets offer good buoyancy (minimum of 15.5 pounds for adults) and are suitable for calm, inland waters where quick rescue is likely. They are less bulky than Type I but may not turn an unconscious person face-up as effectively.
  • Type III PFDs (Flotation Aids): These are designed for comfort and continuous wear. They provide the same buoyancy as Type II (minimum of 15.5 pounds for adults) and are best for calm waters and supervised activities such as kayaking, canoeing, and sailing. They are comfortable and allow for a wide range of motion but are not suitable for rough or remote waters.

2. Consider the Activity

Boating Near Shore

  • Type II PFDs offer a good balance of comfort and safety for boating activities near the shore.

Water Sports (e.g., Kayaking, Paddleboarding)

  • Type III PFDs are ideal for water sports as they provide comfort and freedom of movement.

Specialized Activities (e.g., Windsurfing, Waterskiing)

  • Type V PFDs (Special Use Devices): These are tailored for specific activities and offer both safety and functionality. They include work vests, deck suits, hybrid PFDs, and inflatable PFDs. Some designs, like inflatables, are very comfortable and compact when not inflated.

3. Evaluate Comfort and Fit

Proper Fit

  • Ensure the life jacket fits snugly without being too tight. Adjustable straps can help achieve the right fit. A properly fitted life jacket should not rise above the wearer’s chin or ears when lifted at the shoulders.


  • Consider the design and material for comfort during extended wear. Type III and Type V PFDs are typically more comfortable for active use. Look for features like padded straps and ventilation.

4. Check for Certification and Compliance.


  • Ensure the life jacket meets relevant safety standards, such as those set by the U.S. Coast Guard, ISO, or other local regulatory bodies. Certified life jackets have been tested for performance and safety.


  • Verify that the life jacket is appropriate for your region and activity. Different regions may have specific requirements for life jacket use.

5. Inspect Features and Maintenance Requirements


  • Bright colors and reflective tape enhance visibility in the water, making it easier for rescuers to spot the wearer.


  • Some life jackets, especially inflatable types (Type V), require regular checks and maintenance. Ensure you are prepared to maintain your PFD properly. Regularly inspect for wear and tear, and follow the manufacturer’s instructions for care and maintenance.

6. Additional Tips

  • Child and Pet Life Jackets: Ensure you have appropriately sized life jackets for children and pets. These are specifically designed for smaller body sizes and unique needs.
  • Try Before You Buy: If possible, try on different life jackets to find the best fit and comfort. Some stores may allow you to test them in water.
  • Educate Yourself: Familiarize yourself with the different features and functions of life jackets. Understand how to properly wear and use it in an emergency.
