    Smith Cycle Helmet Technology - MIPS


    Angled impact creates rotational forces. A helmet integrating MIPS creates a sliding layer between the helmet and the head. This allows the helmet's shell to slide relative to the head when hitting the ground.

    This reduces the rotational forces exterted on the head, reducing the potential to damage your brain. This diagram shows the potential for MIPS to reduce violent forces on the brain in certain impacts.

    Smith Mountain Bike Helmets - VaporFit


    Crafted with ease-of-use and superior comfort in mind, the VaporFit fitting system relies on a tried-and-true rotary dial adjustment system integrated with a tuned elastic fit using engineered shapes.

    Each VaporFit system has a full 5cm of rotary adjustability. Additionally, the system can be moved up/down or forward/backward at the attachment points. The result is comfort with a personalized, secure fit.

    Other Helmet Features

    X-Static Performance Lining

    Boasts excellent moisture-wicking properties to draw sweat away from the head, improving heat exchange and comfort. Interwoven with anti-bacterial silver fibres, the lining is also odour-resistant.

    Ultra-Light Single Layer Webbing

    To shave off unnecessary weight an ultra-lightweight single layer of webbing is used on the helmet strap to optimise balance. The webbing is designed to still provide exceptional fitting comfort and security.

    AirEvac Ventilation

    Ventilation channels are placed throughout the helmet shell, positioned to maximise airflow through the helmet when on the move, allowing cool air in and exhausting warm air out to boost comfort during exertion.

    Fitting dimensions for the Smith Portal MIPS are as follows:

    55cm - 59cm
    59cm - 62cm
