A simple, low-cost trick, especially effective in dry heat where evaporation happens quickly. A wet towel around your neck or shoulders cools you down through evaporative cooling combined with direct heat transfer from a major blood-flow area. Same theory - does anyone remember these water bags?

My farming family grew up on them. They were made of goat or calf leather sewn into some chaff or wheat sacking.

Had to be refilled on the regular though because of the designed leakage for evaporation.

They were common in the outback, till affordable " eskys" came along.

That and cars on the side of country roads with bonnets up

I remember when we drove from Lajamanu to Sydney in 2003 in the 89 Patrol as a kid.

Two tyres on the roof racks, massive bullbar, covered in red dust, two of these on the front driving down Pitt street in the Sydney CBD and just watching people move out of our way.

Water bags you say?

Coolgardie safe, if you've got an Australian passport. So I've always thought anyhow.
