Swivvle Reflective Bike Helmet – Sirius in detail

An ultra-visible helmet for riding in style

The Swivvle Sirius was designed in Belgium with a simple ambition: to combine visibility, comfort, and elegance in a single helmet. Thanks to its 360° reflective shell, it captures light to ensure your safety, even at night—no batteries, no cables, and no maintenance. An urban mobility accessory designed for those who want to be seen without sacrificing their style.

Protection, comfort and innovation combined

Beneath its sleek, stylish shell, the Sirius hides some serious safety tech: the MIPS (Multi-directional Impact Protection System) protects the brain from angled impacts, and its Fidlock magnetic buckle allows for easy one-handed adjustment. Weighing just 280g on the head, this helmet remains discreet, well-ventilated, and comfortable to wear, even on long urban rides.

Adapted sizes and ecological commitment

Designed for slimmer figures and female customers, the Sirius comes in three sizes:
• S: ideal for teenagers
• M: equivalent of a male small
• L: corresponds to a masculine M

Certified to CE EN1078, CPSC, and NTA 8776, it's suitable for e-bikes and city use. And because every detail counts, Swivvle is committed to planting a tree for every helmet purchased.
