Product Notes
West Marine CO2 Coastal Automatic Inflatable PFD

The West Marine CO2 Coastal Automatic Inflatable PFD is aimed at adults who want a low-profile life jacket with automatic inflation. The CO2 inflator is the main reason to choose it: it is intended to deploy quickly in an emergency, which is a meaningful advantage for coastal outings and water sports. It is new with tags and built in an adult size. The trade-off is that this inflatable vest will need to be serviced before use, even though it has never been worn. That step is important for anyone who plans to rely on it for safety. If you are comfortable with the servicing requirement, the automatic inflation gives you a compact adult PFD that can be a dependable part of your marine safety survival gear.
Kids Life Vest for Children Under 90lbs

The Kids Life Vest for Children Under 90lbs is a practical family pick. It is designed for young riders under 90 pounds and comes in red, a color that makes a child easier to see. The three adjustable buckles let you tighten the vest for a more secure fit, and the buckle closure helps you get it on quickly. At $80.12, it is the lower-priced option in this comparison, which gives you budget room if you are buying for more than one child. The adult PFD leans on automatic CO2 inflation, while the kids vest leans on its adjustable buckle closure and universal fit. For most family boating trips, that simple setup is a reasonable approach.
Final Choice by Use Case
If you are an adult planning coastal trips and want an inflatable PFD you can service and reuse, choose the West Marine CO2 Coastal Automatic Inflatable PFD Life Vest Adult Jacket.
If you are buying for a child, choose the Kids Life Vest, USCG Approved Type III Life Jacket for Children Under 90lbs.
If you need to equip both an adult and a child, these two vests cover both riders: the adult gets an inflatable PFD, and the child gets a secure youth life jacket.
