From Mark Hankin, who is moving to AZ in May: I have Mustang Ocean Class flotation Vest, Coat and Overalls from when I was fishing many years ago for sale as I won’t need them in AZ.  These are all closed cell foam type and do not rely on an inflatable bladder and are also great for cold weather warmth.  All have built in chest harness.  Overalls have a built-in inflation (manual) pillow in the collar.  Because they were used while fishing, while they don’t smell, they do have some grease stains that could be washed/cleaned out.  All are Unisex Medium in size.  I have attached photos.  If you’re interested, please let me know and I can put you in touch with Mark.
