## Long description

The GIRO Merit MIPS in size M (55–59 cm) is a protective mountain bike helmet engineered for trail and all-mountain riding. It combines a hardened outer shell with an internal impact-absorbing liner and MIPS rotational protection to reduce rotational forces in certain impacts. The helmet features an adjustable fit system and ventilation channels designed to maintain airflow during extended rides. The matte Dark Shark Dune finish provides a low-gloss, neutral aesthetic suitable for both trail and urban use.
Advantages
The integrated MIPS layer offers added rotational impact protection without altering the helmet’s basic fit and profile. The combination of a durable outer shell and an energy-absorbing liner provides multi-impact resistance and reliable impact management. The adjustable retention system allows fine tuning for a secure fit in the 55–59 cm size range, while ventilation channels and internal airflow pathways help regulate temperature on longer rides.
Suitable for
 Trail and all-mountain riding
 Everyday off-road and gravel rides
 Commuting and urban cycling where added protection is desired
 Riders who need a size M helmet (55–59 cm) with good ventilation
Key specifications

 Construction: hardened outer shell with internal impact-absorbing liner
 Fit: adjustable retention system for a secure, customizable fit

How to use
Position the helmet level on your head so the front rim sits just above the eyebrows. Adjust the retention dial or straps until the helmet is snug but comfortable; it should not tilt forward or backward. Fasten the chin strap and adjust the buckle and side sliders so the strap forms a V under each ear and fits securely under the chin. Regularly inspect the helmet before rides for visible damage, cracking, or compromised straps, and replace the helmet after any significant impact.
Usage recommendations
Use the GIRO Merit MIPS helmet for trail and all-mountain cycling and for urban commuting when you require enhanced head protection. Keep the helmet clean by wiping with a damp cloth and mild soap; avoid solvents or high-pressure washing. Replace the helmet after a serious crash or when structural damage is observed. For best performance, ensure correct sizing (55–59 cm) and a properly adjusted retention system before each ride.
