Description

The Giro Terra MIPS Women's Helmet 2026 is a sleek design with advanced functionality for confident, all-mountain performance. Its streamlined design is achieved through the innovative Passive Aggressive Venting System—a discreet yet powerful design that automatically regulates airflow and temperature whether you’re riding, hiking, or standing still. A slight brim and clean, sculpted lines create a refined silhouette that pairs perfectly with Giro goggles for seamless compatibility. With MIPS® technology for added protection, lightweight construction for all-day comfort, and the In Form 2 Fit System for a precise, dialled-in fit, the Terra Mips® offers a barely-there feel with peak performance.

Features:

INTEGRATED MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.

HARDSHELL WITH IN-MOLD HARDBODY™ LOWER WRAP — The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.

IN FORM™ 2 FIT SYSTEM — The In Form 2 Fit System is lighter and lower-profile than the original, and easier to dial in a custom fit in seconds - even with gloves on. An improved dial design provides up to 6cm of adjustment plus enhanced stability.

SEAMLESS COMPATIBILITY — For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function.

STACK VENT TECHNOLOGY — Our Stack Vent was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Aligning the Stack Vent in the helmet with the center vent of the goggle helps keep it clear and fog-free.

PASSIVE AGGRESSIVE VENTING — The discrete exterior vent design and interior channeling (including the liner and padding) combine to create optimal airflow and temperature regulation. This auto-venting technology manages airflow and temperature motion riding, hiking, or standing static.
