Product notes
West Marine Offshore Automatic Life Vest Inflatable Jacket Adult Model SH1F
This pre-owned Offshore vest is the highest listed price in the set at USD 78.95, and it is the only option with a Japan origin in the group. Its automatic inflation is the main draw: the title emphasizes a hands-off approach, and the SH1F model is made for adults. The trade-off is condition and price: you are spending the most on a pre-owned unit, and the manual-only flexibility of the Inshore A/M-24 is not part of this vest's description. If your trips rarely push you into the water, this could still be the automatic vest you want.
West Marine Medalist Life Jacket Adult Med/Large Type III PFD Yellow Navy MB-409
At USD 38.95, the Medalist is the lowest listed price in this comparison. It is also the only adult M/L option whose product name calls out Type III PFD. The yellow and navy colorway makes it the easiest to spot visually in the group. It's pre-owned and made in China, so the purchase is straightforwardly a used jacket at a lower price point. For a day on the water where you want a conventional Type III PFD rather than an inflatable system, this is the one to consider.
2 - WEST MARINE Inshore Automatic/Manual Inflatable Life Jacket Blue
This is the only two-unit listing here, and it comes with CO2 kits and lanyards with whistles. At USD 75.00 for two vests, the per-unit cost comes to USD 37.50 each. The A/M-24 model inflates automatically on immersion and can also be converted to manual-only inflation, which makes it a useful fit for kayaking and canoeing. The limitation is that these are pre-owned units rather than new with tags. Because it's a two-pack, it only makes sense if both vests are going to be used by the people in your group.
WEST MARINE Inshore Automatic/Manual Inflatable Life Jacket Blue - NEW
If you want the A/M-24 in fresh condition, this new-with-tags example from Sh78z-WHSI costs USD 74.97. It keeps the same dual functionality: automatic inflation on immersion, a pull-handle manual option, and oral inflation backup. That is a useful combination for paddlers who expect to get wet. The limitation is that it is a single jacket, so it does not include the extra CO2 kits or whistles that come with the two-unit pre-owned set. At just under the Offshore vest's price, it sits near the higher end of this price spread.
