Trella Mips Helmet - Women's

What Our Gearhead® Experts Are Saying:

"I’ve used this on mixed rides between pavement and dirt, and it’s been easy to adjust mid-ride. The fit stays consistent, and the airflow is noticeable when climbing or riding in warmer conditions."

We choose the Trella Mips Helmet from Giro for rides that shift between pavement, bike paths, and light trail systems, where comfort, protection, and adjustability all matter. It’s built for riders who want one helmet that handles a range of riding styles without needing constant adjustment or second thought.

The helmet integrates the Mips brain protection system directly into the fit architecture, helping to reduce rotational forces in certain impacts while maintaining a low-profile feel. Giro’s Roc Loc Sport Mips fit system provides a wide adjustment range with a simple dial interface, allowing precise tuning even mid-ride. The hardshell with in-mold Hardbody lower wrap enhances durability while keeping overall weight low, and the Universal Fit sizing streamlines the fitting process right out of the box. Large vents are strategically placed to promote consistent airflow, helping regulate temperature during climbs and longer efforts. The internal structure works with the outer shell to maintain coverage without excess bulk, giving the helmet a balanced feel across varied terrain.
