I have a two piece one mm wetsuit that I wear for swimming in summer, which isn’t too hot but protects me from burning. Strangely enough, if it had a hood is would essentially be a birkini.
Had to carry the old dog all the way to the beach and back today, although she managed to swim both ways across the estuary with no problems. I’m going to have big muscly arms by the time summer’s over (will hopefully balance out my cyclist’s thighs).
p.s. For those of tender years and/or the ill informed, here is a picture of the original Emma Peel, played by Diana Rigg in theTV series The Avengers.
