A Jetex baseball cap was also a possibility, but the correct 'Jetex Yellow' yellow would be difficult to source (and potentially insectophilic)
Above: not quite the right yellow and it needs a logo .... hmmm .... starting to look pricey
Ruth vetoed my plans for a pair of 'Jetex Jim' underpants ('still fizzing after sixty years')..
