Aero got cool

Ballista MIPS slices through the wind like no other helmet available, launching you into breakaways and finish line sprints with a wind tunnel-proven design. And with superior venting from our unique internal channeling, this is one aero helmet you can ride every day.

MIPS (Multi-directional Impact Protection System) was developed by brain surgeons and scientists to help reduce rotational forces on the brain caused by angled impacts to the head.
