"I won't say I'm a fan of it but it's a bit Dark Knight, Batman mask," added one of the Tour de France's greatest ever sprinter,
Robbie McEwen, a 12-time stage winner at the Grand Boucle, with three Green Jersey wins under his belt.
Surely if Groenewegen wins the stage 3 bunch sprint, we will see the nose guards everywhere before too long. Take a look at the item in question down below and let us know what you think about it!
