How to use
Place the helmet on your head so the front edge sits just above the eyebrows and the rear covers the base of the skull. Use the retention dial or adjustment mechanism to tighten the fit until the helmet feels secure but comfortable; it should not move excessively when you shake your head. Adjust the side straps to form a V shape under each ear and fasten the buckle under the chin, allowing one or two fingers of space between the strap and your chin. Regularly inspect the helmet for visible damage and replace it after any significant impact or when signs of material wear appear.
Usage recommendations
The helmet is intended for mountain biking and trail use; choose the correct size (51–55 cm) and ensure the retention system is adjusted before each ride. Clean with mild soap and water, avoid strong solvents or abrasive cleaners, and store the helmet away from direct sunlight to preserve the Matte Trail Green finish and material integrity.Note: This description references functional features for fit, ventilation and protection appropriate to the GIRO Radix MTB helmet in size S.
