Trews, call them TREWS! It's the only acceptable way of asking :winks:. There was this recent thread that might help. The warmest pants I own are a pair of German Army wool trousers I believe wool used would be in the 16oz or higher range. When I was married in Jamaica I wore an antique wool tux possibly in the 12 - 14oz range and was not too uncomfortable in it even during the midday sun (Red Stripe helped). If I recall, you're in the warmer climes. I wonder if PV would also be a viable option.
