Techs & Features

Mips Evolve Core

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.

TransTextura™

TransTextura™

Permanent denier gradient transfer technology uses capillary action to pull moisture away from the skin to the fabric surface for rapid evaporation and quick drying.

TransTextura Plus™

All of the benefits of TransTexura™ with the addition of anti-microbial functionality to help neutralize bacteria that causes odors.

  • Anti-microbial
  • Anti-odor

Virginia Tech 5 Star Rating

In collaboration with the Insurance Institute for Highway Safety, the Virginia Tech Helmet lab tests helmets using the STAR evaluation system. The 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, with 4 and 5 star ratings being the most highly recommended. Read more.
