Seems some people in the paddling industry have a cavalier approach to wearing PFDs. The kayak fishing group is shown wearing them only about half the time (national magazine photos). Regarding the general attitude in this article, I have to side with Chris. Personally I feel that individual body type, etc. has a profound affect on one becoming hypothermic. I've capsized in the North Pacific off Kodiak wearing just fleece top/rain pants under a PFD and casually re-entered my boat - and not changing for another hour. I've also seen a person in a complete survivor suit (the orange gumby suit) become hypothermic with 45 seconds of hitting the water. The old kayaking addage "Dress for the water not for the air" is well founded and for good reasons.
