I have found repeated references to this unit as an emergency body cover in marine situations. Doug describes the product very well and provides links to the manufacturer's site. My question is this:

Has anyone had the opportunity to field test this bag?

I am seeking information and not a product endorsement. At the current price I'm thinking about adding 4 to my boat's ditch bag. While the "something is better than nothing" argument may hold up, I see no point in creating a false sense of security to save a few bucks.

BTW, my offshore fishing is confined to 15-20 miles out max. We do not cross the bar if there is a sliver of doubt about conditions presently or in the next 10 hrs.
