Giro Trella MIPS

MIPS stands for Multi-directional Impact Protection System. It is a low-friction layer inside the helmet that allows the shell to slide slightly during an angled impact, which helps redirect rotational energy away from your head.

Yes, the visor is designed to be removable. You can easily detach it for a more streamlined profile or keep it on when you need extra shade from the sun.

The Roc Loc Sport system uses a dial at the back of the helmet that allows you to tighten or loosen the fit with one hand. It provides a secure, stable feel that accommodates a wide range of head shapes and sizes.

With 18 vents, this helmet is designed for consistent airflow. The ventilation channels are positioned to pull cool air in and push warm air out, making it a solid choice for warmer weather.

The Trella MIPS includes integrated reflective elements that help you stand out to drivers in low-light conditions. While it is a great safety feature, we always recommend pairing it with active bike lights for maximum visibility.

This helmet is primarily designed for commuting and recreational cycling on paved surfaces or light paths. While it offers excellent protection, it lacks the extended rear coverage and specific features found on dedicated mountain bike helmets.
