Spherical Technology is a ball-and-socket design that allows the outer liner of the helmet to rotate around the inner liner during a crash, redirecting impact forces away from the brain.
Yes, the helmet features an adjustable visor to accommodate goggles or changing light conditions.
Giro recommends replacing any helmet that has been involved in a significant impact, or every three to five years depending on frequency of use and material degradation.
Yes, the Merit Spherical utilizes a Mips brain protection system as part of its integral design.
We recommend hand washing the padding with mild soap and cold water to preserve the anti-microbial finish and shape of the foam.
Adjust the Roc Loc dial at the back of the helmet until snug and ensure the side strap triangles are positioned just below your ears.
Remove the Ionic+ pads and hand wash them with a gentle detergent, then allow them to air dry completely.
Check the mounting points to ensure the visor is fully clicked into the designated slots; if movement persists, contact support for replacement hardware.
To set up your helmet, start by loosening the Roc Loc Trail Air dial completely. Place the helmet on your head and tighten the rear dial until it is snug but comfortable. Ensure the chin strap is adjusted so that it sits firmly against your throat without being constrictive. For care, the Ionic+ padding should be removed periodically and washed in cold water with mild detergent and air-dried to maintain anti-microbial properties. Clean the outer shell with a soft cloth and non-abrasive soap to protect the finish.
