Those who go fast always want to go faster. That's why we put so much emphasis on the aerodynamics of the Profit Aero. The Profit Aero's architecture ensures ventilation inside the helmet while cutting through the wind like an F-15. But let's be realistic. To be lightning fast, you need to feel safe. That's why it features the Boa® fit system. Not only is it the best-known tightening system, it's also the best. Easy to use, comfortable and millimetric. Once you've adjusted the Fidlock® magnetic loop with one hand, you'll understand why we've been congratulated by Mario Mola, the world triathlon champion.
