I still haven't had a chance to test out the 100g in the ocean (going to this weekend, but I'll also be taking some extra layers and my dual layer polartech as a backup!), but I've noticed people vary greatly in how much insulation they need. Some is based on drysuit, I dive a compressed neoprene that offers more insulation by itself than a shell will, at least at moderate depths (at 100ft that insulation is lost and I notice the chill more).
I'll report back on how it goes next week. His warmest garments are the 4 way Antarctica ones.
