Force India driver Nico Hulkenberg has revealed his secret to keeping cool in the soaring temperatures at Sepang during the Malaysian Grand Prix- by wearing frozen underwear.
While drivers like Jenson Button have used the help of cooling vests, the driver for Silverstone-based Force India has gone one better.
According to the Mirror, the German ace has resorted to keeping his boxers in the freezer and then wearing them to ward off the 50-degree Celsius cockpit heat at the start of the hottest race of the season in Sepang
Hulkenberg said that he makes his underwear wet, puts them in the freezer and then take them out just five minutes before dressing to 'knock them soft'.
