Hi, I am in Melbourne, just spotted your note, am wearing a 13 oz woollen kilt as I write this but have been dancing indoors so was fine, I was at the Celtic festival near the beach at Portarlington over the weekend and it is near the shortest day and hardy hot so I wore a 10 yard 16 oz woollen kilt and was very comfortable! I have also worn it on century temp days and a 13 oz in deep winter but obviously one is warmer than the other but the difference is not as great as you may think. It may be the heavy one takes in less sun heat being thicker, the breezes beneath are little different so get what you like but the heavy ones definately look and stay better longer. PV is cheap and quite reasonable and similar but not as good as 13 oz wool whereas acrylic is cheapest and best for comfort summer or winter but will never stay looking good that long and is light so very iffy when windy! Hope this helps.
