Ey up Nobber, nowt wrong wi leafers or flat caps for that matter, the former does my beasty just fine for the last 44 years and who cares what they do to backs - manual work has knackered mine anyway, flat cap keeps your head warm and your ears exposed - useful for hearing movement of your quarry - obviously if you are a townie then its not much use. Flat caps have the added benefit of being largely British made, therefore helping our economy, rather than our oriental or indian friends that makes most of the beanie or baseball type caps
