Thanks to an open and airy design, with 18 vents to encourage cooling airflow, and a weight reducing In-Mold construction with hardbody shell, the Women's Trella Helmet is versatile and tough enough to take on a gravel adventure, bike packing tour or enjoying an urban spin to meet friends in town. The Roc Loc Sport fit system is incredibly easy to use and gives you the perfect fit every time and it integrates perfectly with the Multi-Directional Impact Protection System (MIPS) to deliver class-leading protection and energy redirection from impacts.
What is MIPS?
• MIPS is a Brain Protection System
• Rotational motion can cause brain injuries
• The low friction layer allows a sliding movement of 10–15 mm, in all directions, reducing rotational motion to the brain during impact
• MIPS adds protection
