Own the night with the Voss 991 Stardust, a lightweight carbon fiber motorcycle helmet that blends advanced safety and standout style.

The genuine carbon fiber shell keeps weight around 1400 g while meeting DOT FMVSS 218 standards. MIPS brain protection technology helps reduce rotational forces from certain impacts. A wind-tunnel developed shell with sharper edges and multi-port airflow enhances stability and ventilation. The changeable spoiler fine-tunes aerodynamics to reduce buffeting, increase high-speed stability, and improve airflow balance in different riding positions. See more of the road with the Max Vision spring-loaded face shield, Pinlock 70 prepared for anti-fog clarity and a 200º field of view. Drop the integrated VIVS internal sun visor with UV380 protection in seconds, tool-free. The DryTech moisture-wicking liner is removable and hand washable for long-ride comfort, and the SCDS Safety Cheek-pad Detachment System aids quick pad removal. Bluetooth-ready speaker pockets fit 40 mm drivers for easy comms integration. An integrated neck gaiter and stainless steel micrometric quick-release deliver secure, everyday convenience. The cosmic Stardust gloss finish shifts between teal, violet, and blue tones depending on light, so every ride turns heads.

991 FEATURES

Understanding the Mips® safety system

Integrated into select Voss helmets as part of a multi-layered approach to safety.

Most real-world motorcycle crashes involve angled impacts. The Mips safety system is designed to help reduce rotational motion that might otherwise be transferred to the rider’s head.

What Is the Pinlock® anti-fog technology?

The Pinlock® anti-fog technology is a secondary inner lens that attaches to the inside of a compatible helmet visor using two mounting pins.

The insert creates a sealed air pocket between the outer visor and the inner lens. This dual-pane construction helps reduce temperature differences across the visor surface, which is designed to minimize fog formation.

The system works similarly to double-pane insulation, helping maintain clearer vision across a wide range of riding conditions.

Excellent Fit

Love the 991 helmet. Fits true to size, I wear glasses so it's a perfect fit love the look, love the ratcheting strap system and the photochromatic lens. I have the unit 1 faro helmets with MIPS technology for my e-bikes so when VOSS came out with MIPS for a full faced motorcycle helmet I had to get it knowing the benefits it provides in case of an accident. The inside liner system unbuttoning and rebuttoning after putting in a Bluetooth system is a little challenging and may still need work, not sure why the liner covers the speaker and sounds muffled still after I removed the speaker liner hoping it would sound louder. A little constructive criticism for them to improve the speaker area on their next model upgrade. Definitely not a deal breaker. I say get your Voss Helmet before their sold out.Thank you Voss!
