A cool headband

Iknow that our weather here is very hot and everybody uses airconditioning inside buildings over here. But once in a while, you're bound to go out, so....

How leh ?

This might be the solution. The cooling effect lasts between 30 and 60 minutes. The dimensions of this headband are 90x65x22mm

Cool leh !!! ( I mean ..... cool in temperature... )
