Bontrager's Ballista bike helmet was Jen's Voigt's aero choice for his hour record. Ballista is perfect for cyclists who want to cheat the wind and gain an advantage on every ride. The air vents are strategically placed to keep you cool and fast while the Headmaster II fit system keeps it snug.
Bontrager features a 30 day return policy and a crash replacement guarantee on bike helmets to keep you covered during your first year of ownership.

I absolutely love this helmet, have tried many and this is by far my favorite one. The aero effects are noticeable, studies have shown that a good aero helmet offer aero benefits similar to aero 50mm wheels.
