    Fast Lens Changes for Your MTB Goggles Thanks to a Practical Twist-Lock System

    With the innovative twist-lock system, the lenses of the downhill goggles can be changed quickly and easily. This allows you to optimally adapt your MTB cross goggles to changing light conditions. Several lens options are available with a durable nano-coating against annoying fogging – from clear lenses for poor visibility to tinted versions for sunny trails. For additional clarity in muddy conditions, optional tear-off films are available for the CAT.0 lenses.

    Mountain Bike Goggles with Maximum Ventilation

    The LINE stands out with its well-designed ventilation system. Air-flow channels in the frame ensure optimal air circulation and prevent the MTB downhill goggles from fogging up. The soft foam adapts perfectly to your face, while the extra-wide 50 mm strap ensures a secure fit – even during intense runs. This keeps your MTB goggles stable and comfortable at all times.

    A Downhill Goggle to Match Your Style

    The mountain bike goggles are available in striking designs such as Black Cloud, Tropic, Polygon, and Scrap Yard. The Polygon and Scrap Yard designs were created in collaboration with UNLEAZHED, a specialist for bike accessories and protective films – allowing you to perfectly match your style to your bike.
