A drysuit for me too.
I learned my lesson the hard way , a few years ago, when I capsized a kayak a mile off shore in mid December near Millport, Scotland. I was wearing simple waterproofs on top of layers of woollen and cotton clothes.
So I know first hand the gasp reflex when you first go under, I know how quickly I lost my arm strength trying to get back into the kayak over its rear deck while my two companions rafted beside it.
I know the feeling of hypothermia making me feel drunk after only 10 minutes in the water. I also know as soon as I got to the shore, fifteen minutes later, my problems had only just begun. I collapsed in a heap after being on dry land for only a couple of minutes. It was the bitter cold wind cutting into sodden clothing that was now worse than the relative warmth of the freezing cold winter sea.
I doubt if I would be writing this today if it had not been for my companions being better prepared than myself. They put me in a survival bag that stopped the wind chill. They put me in their spare dry clothes as I didn’t even carry a change of clothes back then .. then gave me hot soup until I started to feel better.
I confess .. I have fallen in since, when wearing my drysuit.. clambered back into the boat and continued on my adventure ... non the worse for my surprise dip.
Its the best piece of boating clothing I have ever bought.
