Pete,

I spent 6 years in Commandos - I know what works and what doesn't from spening many hours
in Zodiac's in Bass Straight in the middle of Winter !!!

The thermals work - I wearthe lightweight ones all winter down in Melbourne.
I will find out where to get the thicker ones.

I agree with the previous poster - you will need something that is Windproof
as that can be the killer.
