Choosing marine safety survival gear usually comes down to who is wearing it and what kind of water you're facing. That's exactly the split between these two West Marine life jackets. The Child's West Marine Life Jacket Type 3 is listed at USD 9.95 and is meant for a small child. The West Marine CO2 Coastal Automatic Inflatable PFD Life Vest Adult Jacket is listed at USD 99.99 and is built around an automatic CO2 inflator for coast use.
Quick verdict
If the jacket is for a child in the 30-to-50-pound range and you're okay with pre-owned gear, the Child's Type 3 is the practical lower-price pick. If you need a coast-ready inflatable that you'll service before use, the CO2 Coastal Automatic Inflatable PFD is the more capable choice.

Where each wins

- West Marine CO2 Coastal Automatic Inflatable PFD wins for an automatic inflatable design that suits coastal boating.
Child's West Marine Life Jacket Type 3

At the lower listed price, this pre-owned vest is described as a child's Type 3 life jacket rated for 30 to 50 pounds with US CG approved flotation. The previous owner kept it indoors after a few uses and says the buckles are in great condition and the zipper works. The trade-off is clear: there are a few small stains on the back and inside. If you're comfortable with that and need a small-child vest, this is a direct way to get into a West Marine life jacket for a limited outlay.
West Marine CO2 Coastal Automatic Inflatable PFD Life Vest Adult Jacket

This automatic inflatable PFD is listed as new with tags at the higher price in the comparison. It is designed for an adult wearer and uses a CO2 inflator that deploys automatically for coastal water sports. The listing also states that it will need to be serviced even though it has never been used, which is a real consideration before you put it on. The strength here is the new condition and automatic system; the catch is the service step and the higher listed price.
Final choice by use case
For a small child and the lower listed price, pick the Child's West Marine Life Jacket Type 3. For coastal boating where an automatic inflatable is the priority, choose the West Marine CO2 Coastal Automatic Inflatable PFD and plan for the service step.
