I see your wearing a drysuit, were you in the water trying to pick the best one?
Not sure why the eyerolling. The salt-water in the PNW is freaking cold. Not Alaska cold, but cold enough that without immersion protection you'd lose a significant amount of the ability to operate your extremities in a couple minutes. To the point that within 2-5 minutes (depending on actual water temperature and individual differences) you would not be capable of independantly climbing into a boat or hauling yourself back onto your kayak.
Getting dumped off a kayak in that water is likely lethal if you don't have anyone within earshot or radio range without a drysuit. With a drysuit (and PFD) you at least have a chance of making contact with someone and getting rescued before hypothermia kills you. The dry suit, with appropriate insulating layers underneath, increases survival time from 15 minutes to many hours.
And if you're going to mock, at least be able to tell the difference between a surface sports dry suit (e.g. the one I'm wearing) and a diving drysuit. Strictly speaking, the one I'm wearing is a semi-dry suit because it has a neoprene neck gasket rather than latex (far more comfortable and good enough when lengthy submersion is not expected).
