Manifest Spherical Helmet
Giro Manifest Spherical Helmet Review
Tested and reviewed for bikepacking use
Giro's Manifest uses their Spherical Technology, a ball-and-socket design that replaces traditional MIPS. Two foam layers can rotate independently to redirect rotational energy. The result is one of the lightest and best-ventilated trail helmets available.
Who Is the Giro Manifest Spherical Helmet Best For?
Riders who want top-tier protection and ventilation in a lightweight trail helmet. If that describes your riding style, the Manifest Spherical Helmet should be at the top of your shortlist. It sits in the Safety Gear category alongside 9other products we've reviewed.
How It Compares
At 310g and $250, the Manifest Spherical Helmet is 210g heavier than the lightest option in this category (the Garmin inReach Mini 2 at 100g). The most budget-friendly option is the Adventure Medical Kits Ultralight .5 First Aid Kit at $18.
The price-to-weight ratio comes in at $81 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
