Features
- Keep your noggin safe, cool and comfortable on the trail in the Giro Manifest Spherical Mips bike helmet. It’s well ventilated and provides deep coverage for a feel and fit you can set and forget.
- Spherical technology with ball-and-socket design powered by Mips® helps redirect impact away from the brain by allowing the outer liner to rotate around inner during a crash
- Spherical design also eliminates contact with hard plastic or slip-planes against the skin
- Integrated Mips brain protection system; the goal of integrated Mips-equipped Giro helmets is to reduce rotational forces
- Giro believes that helmets equipped with Mips technology can reduce the amount of rotational force that may be transferred to a rider’s brain in certain impacts
- All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards
- Progressive layering uses 2 different densities of EPS foam liners to address high- and low-speed impacts for more comprehensive energy management
- Structural integrity is bolstered by the shatter-resistant and translucent AURA reinforcing arch that runs throughout the helmet
- Adjustable moto-style screw-in visor with adjustment mechanism that lets you move the visor up and down in indexed steps
- These steps include 3 riding positions plus a high position for goggles storage above your brow; the design allows you to easily adjust your visor with one hand while riding

- IONIC+ padding with pure silver, the secret ingredient that gives it the power to provide natural, permanent odor protection and keeps your helmet feeling fresh
