I already have some pretty heavy duty thinsulate underwear, plus a Scubapro
drysuit system which includes dry hood, dry gloves and FFM. I take keeping
warm VERY seriously and dislike having any cold water in contact with any
part of my body.

The gel packs are of limited value. The types I am refering to can be used
but definately not close to the skin. Like any piece of new equipment the
best thing is to experiment with them on easy dives. I have used them
successfully many times.
