The Giro Merit Spherical Helmet is a top - notch choice for trail riders. Its Spherical Technology, with a ball - and - socket design, offers excellent ventilation, deep coverage, and luxurious comfort.

The Roc Loc® Trail Air fit system allows for quick and easy fit and stability adjustments, and the plush Ionic+ padding absorbs sweat well and has permanent antimicrobial properties to fight odor. It features an in - mold polycarbonate shell with EPS liner, full lower hardbody coverage, and a progressive layering construction. The adjustable moto - style screw - in visor is a great addition. It weighs 360G (Size Medium CPSC) or 350G (Size Medium CE) and meets the US CPSC Safety standard for bicycle helmets for those aged 5 and older, as well as the EU's CE EN1078 certification.

You can adjust the moto - style screw - in visor to your preferred position for better visibility. When riding, the helmet's ventilation system will keep you cool. Just enjoy your trail ride! As for maintenance, clean the helmet regularly. You can use a mild soap and water to clean the exterior and the Ionic+ padding. Let it air - dry completely before using it again.

If there's any crack or significant impact damage, it's time to replace your helmet to ensure your safety.
