New Hat from Tilley
This seems to be just what you have been asking for - only a little bit better! We frequently get asked for hats like the ones the French Foreign Legion wore which protect the back of the neck from sunburn. Now Tilley have come up with a brilliant solution with a sun shield cape that folds out from a pouch hidden in the brim. So it is there when you need it and not there when you don't need it.
Nice colour too!
