Emilio…if you made a hot “thick suit” it should sell well in countries like Canada…even in most parts of Ontario our open water season is barely June 1 to Sep 15th WITH wetsuit…anything that is warmer and floats better will make us faster in races AND extend the season by a few weeks on each side! I bet the same applies to northern Europe, and parts of New Zealand.
Yep, I have swam in Vancouver Bay, as well as in Lake Hays and Milford Sounds on the South Island of New Zealand…cold water that cold hurts!
