With the Manifest, Giro shows in many areas what an ingenious helmet should look like. The spherical system is technically top-notch. The weight is still OK, but the high price is a pain.
The MIPS Spherical security system sits seamlessly between two layers of EPS foam and absorbs rotational forces during crashes without compromising ventilation.
The Roc Loc Trail Air system allows for precise fit adjustment to ensure a secure hold in rough terrain.
The helmet weighs 346g and is specifically designed for trail use and wearing with goggles.
