Aero got cool

The Ballista MIPS road helmet projects racers to their target just like the ancient Greek missile weapon it was named after. Thanks to a wind tunnel-proven design and superior venting with our unique internal channeling, Ballista launches you to the front of peloton breakaways and sprint-line finishes.

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