From the sun! Never thought I'd ever say this. Every time the sun appears in Northern England, half the male population go shirtless, and that includes me. But the good ole Neighbourhood Quack has had cause to give me advice.
Now, a sunhat doesn't effectively cover the back o the neck, though a sombrero might. Riding a bike with a sombrero ain't gonna win any races, nor will the hat remain in its designated position.
So, short of becoming an aged rocker, or an arab, what would you do?
