In collaboration with the Insurance Institute for Highway Safety, Virginia Tech have rated a total of 128 bike helmets using the STAR evaluation system. The bicycle helmet impact tests evaluate a helmet's ability to reduce linear acceleration and rotational velocity of the head resulting from a range of impacts a cyclist might experience. Helmets with more stars provide a reduction in concussion risk for these impacts compared to helmets with less stars. Read more.

Liv is committed to cycling for a better future. We know the trail to reaching net zero is a long and challenging one, which is why we are leading the way with innovative solutions. We are reinventing how we work with manufacturing partners and investing in new technologies to help reduce our overall environmental impact. Our Enviro Mark tells this story of transformation. When you see this symbol, you’re seeing a product that’s designed with the planet in mind, including recycled materials and more sustainable manufacturing processes.

Mips Evolve Core is designed to add protection in helmets against the rotational motion. The rotational motion is a combination of rotational energy (angular velocity) and rotational forces (from angular acceleration) that both affects the brain and increases the risk for minor and severe brain injuries. Mips has been scientifically proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.
