Giro Fixture II MIPS Mountain Bike Helmet - Universal Fit and MIPS

In this review the Giro Fixture II MIPS is judged on fit, protection, and everyday usability. It is best for riders who want a reliable, lightweight helmet with modern safety features and straightforward sizing; the biggest reason to buy is the integrated MIPS system that helps redirect rotational forces in a crash while still offering good ventilation for rides of an hour or two. The helmet's universal women sizing (50-57 cm) and simple rear adjustment make it easy to get a secure fit right out of the box.

Key Features

• Market leading protection: Engineered in Giro's testing lab to provide consistent impact management for everyday mountain biking and trail use.
• Integrated MIPS: The Multi-Directional Impact Protection System is built in to help reduce rotational energy transfer during certain impacts.
• Ventilation: Eighteen Wind Tunnel vents with internal channeling keep airflow moving to help prevent overheating on short to medium rides.
• Rugged construction: In-molding construction bonds the shell to the EPS liner for durable protection and a lightweight feel.
• Universal fit sizing: The 50-57 cm range and rear adjustment dial provide an immediate, comfortable fit for many head shapes without lengthy adjustments.

Who It's For

The Giro Fixture II MIPS is well suited to casual and commuter cyclists, recreational mountain bikers, and parents buying a single helmet to share among family members within the 50-57 cm range. Its combination of lightweight feel, breathable vents, and an easy-to-use adjustment system makes it a good match for 1-2 hour rides and varied trail conditions.

Racers or riders seeking highly specialized helmets with extreme ventilation profiles or race-oriented aerodynamic shaping may prefer other models. Also, riders who need sizing outside the 50-57 cm band should look at other sizes in Giro's range.
