Thanks for this info - I'll pack my rain jacket (it seems to insulate pretty well). We have the lemon eucalyptus but I plan to get the regular deet stuff too, just in case.
Yes, the last two posts make excellent points, which I had neglected in my post. The little swester that was all I needed was after diving whilst dry and going for dinner. A wind breaker for the boat rather have and not need, than need and not have. And, yes KathyA, I definitely agree that planes can be very cold and I have a complete different set of travel clothes, including a scarf, that I wear when traveling.
