When you're sorting through marine safety survival options, the core decision is often whether you want a life jacket that inflates automatically when it hits the water or one you deliberately activate yourself. The two West Marine products here take those different paths. One is a vest-style automatic CO2 inflatable. The other is a belt-style manual inflatable. Here's how they compare for a shopper who wants concrete guidance.
Quick Verdict
If your priority is hands-free buoyancy in a vest that covers your torso, the West Marine CO2 Coastal Automatic Inflatable PFD Life Vest Adult Jacket is the automatic choice. If you'd rather spend less and keep a lower-profile belt-style inflatable that you activate manually, the WEST MARINE M-24 Manual Inflatable Life Jacket Belt fits that approach. The listed price difference between the two is USD 45.99.

Product Notes
West Marine CO2 Coastal Automatic Inflatable PFD Life Vest Adult Jacket

This vest sits on the higher-priced side of this comparison, and the automatic CO2 inflator is its standout feature. Because it's a vest, it gives fuller coverage across the chest and back. The main reason to choose it is the automatic deployment: in an emergency, it inflates without requiring you to find and pull a handle, which is a real advantage if your hands are busy or you're unexpectedly in the water. The limitation to weigh is that it needs to be serviced before use. That means this isn't a grab-and-go piece; plan to have it serviced before relying on it on the water.
WEST MARINE M-24 Manual Inflatable Life Jacket Belt

This belt is the lower-priced alternative in this pairing. It's a manual inflatable, so you have to activate the inflation yourself rather than relying on automatic contact with the water. The belt-style design keeps the unit around your waist and its country of origin is the United States. The reason to choose it is that compact, lower-priced profile. It gives you a different wearing option than a vest without the same amount of torso coverage. The limitation is that the exterior of the pouches shows some markings from storage, so you'll receive it with visible cosmetic blemishes even though it's technically new.
Final Choice by Use Case
Choose the West Marine CO2 Coastal Automatic Inflatable PFD Life Vest if you want an automatic vest-style life jacket and you're prepared to have it serviced before relying on it. Choose the WEST MARINE M-24 Manual Inflatable Life Jacket Belt if you want a belt-style inflatable and you're comfortable with manual activation plus a few storage marks on the pouches.
