The Terra MIPS Helmet offers sharp lines and smooth style while offering the advanced protection of MIPS, sophisticated ventilation, and on-the-fly vertical tuning capability. It delivers on the promise of an ultra-lightweight perfect fit in a sleek, modern design.

The streamlined profile is achieved through the new Passive Aggressive Venting system, a discreet yet powerful system that automatically manages airflow and temperature while in-motion riding, hiking, or standing static. The overall look is finished with a slight brim and subtle lines for Seamless Compatibility with Giro goggles. The Terra MIPS Helmet also features MIPS technology, lightweight construction, and the dialed-in fit of the In Form 2 Fit system for a barely-there feel.

Size Guide


Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.

Small 52 - 55.5 cm
Medium 55.5 - 59 cm

Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering vision. Once you’ve got the right size, you can adjust the fit.


Step 1: Adjust the fit system at the rear of the helmet for a snug, secure fit. Some helmets also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.

Step 2: Adjust the straps so that they sit just below the earlobes.

Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.

Step 4: Adjust the interior pads if needed.

Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.
