Manifest The Best.

Why compromise? For the riders that demand the best equipment, meet Giro's new Manifest™ Spherical helmet. With Spherical Technology™, best-in-class ventilation, full coverage and luxurious comfort, Manifest is the most premium trail riding helmet available.

Among the Manifest's extraordinary features is Spherical Technology which utilizes a ball-and-socket design to redirect impact forces. Developed in Giro's test lab in partnership with MIPS®, Spherical Technology allows the outer liner to rotate around the inner liner during a crash, and eliminates contact with a hard plastic slip-plane against skin. Another major benefit of Spherical Technology is progressive layering — dual-density foam liners designed to address high- and low-speed impacts for more comprehensive energy management.

The Best Ventilation on Dirt.

As you push your limits on the pedals, you'll appreciate this helmet's wide-open airflow. The AURA reinforcing arch bolsters structural integrity while allowing air to flow freely into a series of massive Wind Tunnel™ vents and internal channeling. Comfort and sweat absorption are enhanced by quick-drying antimicrobial XT2 padding.

You'll notice this cooling power when you're hammering in the heat and it's backed up by Giro's test results.

Luxurious Comfort.

Fit and positioning adjustments are achieved with a redesigned Roc Loc® Trail Air fit system that offers dynamic strength and UV-resistance while improving ventilation and comfort. And it almost goes without saying, the Manifest's™ sophisticated style and compact design raises the bar for performance and style.

  • Spherical Technology™ - powered by MIPS® is a unique ball-and-socket design redirecting impact forces, bringing market-leading design, performance and brain protection together without compromising comfort, ventilation, weight or style
  • Progressive layering is designed to address high and low-speed impacts
  • Wide-Open ventilation is achieved through a 3mm gap between the brow of the helmet and the forehead, allowing air to flow up and through the helmet
  • MIPS® Brain Protection System helps redirect impact forces away from the brain
  • AURA reinforcing arch bolsters structural integrity while allowing air to flow freely
  • Fidlock® magnetic buckle offers fast and secure retention
  • Adjustable moto-style screw-in visor offers 15-degrees of movement to shield the sun or store goggles
  • XT2® anti-microbial padding is quick-drying and fights off odor and bacteria, helping the helmet stay fresher, longer
  • The goggle gripper is a bonded rubber gripper on the back of the helmet holds the goggle strap firmly
  • Integrated eyewear grippers provide plenty of room for sunglasses without sacrificing coverage
  • Lightweight webbing features built-in pads, which comfortably cradle the occipital lobe while shredding even the roughest descents
  • Reflective decals on rear of the helmet are nearly invisible, yet offer vibrant reflectivity the moment light shines on it

    Very Comfortable helmet

    I've owned the road version of Giro's spherical MIPS helmet, the Aether for the last two years and I love it. So as soon as this version for Mountain Biking came out I really wanted it!

    It's very comfortable not having any of the MIPS plastic against your scalp but still having the safety benefits of MIPS. It's also very light weight, and the fit is perfect. I have a more oval head, most helmets sit a bit high above my ears, but this one comes down perfectly, a quarter inch above my ear, and just above my eye brows. It also covers the back of my head nicely.

    The vents are quite generous, I'll be happy to have that ventilation on the warm days! It's worth mentioning too that the colors are way better in person. The matte gray has a slight bit of blue to it and the lower portion is kind of marble like. Very nice looking!
