Many people seem to think that having as minimal clothing as possible makes you feel cool. That is not the case.

Look what people living in sahara wears. Loose fitting garments with minimal skin exposure.

So for the western individual a loose fitting cotton or linen shirt and trousers or shorts and a hat is the way to go.

When itīs 30°C here I felt quite comfortable in a 50/50 NyCo t-shirt, safari-type vest, boonie, shorts and sandals.
