Thank you for viewing. This is an old-style life jacket, likely an automatically inflating type. I haven't fallen into the water, so I can't guarantee it will work. I believe there is gas inside, but I haven't confirmed this either, so please understand. I've used it a few times on a boat. There's some minor soiling, but it's in relatively good condition, so please judge from the images. I'm looking for someone who understands used fishing tackle. Due to the gas inside, please refrain from purchasing if you are in an area that requires air transport.
