Smiffmog seeing as you were in Brittany did you consider a beret? Barbour flat cap in green waxed[actually sylkoil] finish is my choice, Tilley are great [I've sold hundreds of them] but not for Mogging unless your middle name is 'Chump', what ever you choose it needs to be a close fit, or you will literally wave your hat goodbye when speedo hits 90, though Tilley would give you 50% towards a new one should that happen [within 2yrs of purchase] cowboy
