Should you wear a base layer under your jersey in summer as well as winter? We quiz the experts – and start a heated debate
You’ve seen it on mountain stages of the Giro d’Italia, Tour de France and Vuelta a Espana. As the sun beats down and riders push themselves to their physical limits, they unzip their jerseys. Some reveal an emaciated bare chest; others show off a base layer beneath the jersey.
But who’s got it right?
