Fabric suggestions for the hot

[Balfour]

^ Thanks. I run hot and always opt for non-silk linings - I need all the advantages I can get here, even in the mild UK climate.

I still remember many years ago a business trip as a young chap to DC in late July: in 11-12 ounce fully lined worsted. I melted outside AC!

I worked in Sydney in my previous life and working in SE Asia now.

Generally Stiva was right except I found that in OZ where the weather tends to be dry, I can wear my tropical weight / fresco buggy lined suit for most of summer days without drenched in sweat.
Nevertheless, in a humid climate where I'm living now, at 32 degree average even wearing the lightest shirt and trousers I'm sweating like pig.

Dry climate: Lightweight half / buggy / unlined suit in 7-8 oz works fine.
Humid climate: Wear suit only in a climate controlled environment.

I guess climate plays a part as well as one's body heat.
