First day of the summer today and (ahem) I note that because I prepared well for a hard winter, the lifejacket that has been a tight fit since I bought it is now in danger of restricting oxygen and circulation when I wear it with an (ahem) extremely
thickly padded flotation suit
So, can you buy any sort of an extension harness for fat people? Google found some in the States with completely the wrong fitting but that was all. It's a bog standard Hammar jacket from lifejackets.co.uk with a square of stainless steel on each end of the main retaining strap, you swivel one sideways and push it through the other and then it can't pull back through. Not sure if they all use the same concept or not. What would be ideal is the same arrangement on the end of about 3-4 inches of webbing.
Do the 'offshore' 275N jackets that are designed to be worn over foul weather clothing / survival suits generally have bigger straps? I think in the long term that would be a better bet - and it's something I have been thinking about for a while anyway but I need a more immediate solution.
