Jet Greenwich

Important note

Because we offer more than a hundred colour and trim combinations across several sizes, every helmet is produced to order. All pieces are customized and hand-assembled.

Please allow up to six weeks for production before shipping.

Size instructions and certifications

Measure the circumference of your head at its widest point (usually about 2.5 cm or 1 inch above your eyebrows), then compare with our size table.

The helmet should fit firmly for proper protection; the interior padding will settle and can compress slightly in the areas where your head needs more room.

Safety standards

Our helmets are certified to the relevant safety standards for the market in which they are delivered (for example ECE 22.05, DOT, JIS, where applicable).

Visor system

The Jet helmet is equipped with an articulated visor that can cover the full face, improving comfort in changing weather and at higher speeds.

Each Jet comes with three interchangeable visors: clear, light smoke and dark smoke.

The visors can be swapped in seconds thanks to the quick-release pivot system on the sides of the helmet.

Pivot kits in different finishes are available separately in the accessories section.

Genuine craftsmanship

• Chrome, black leather or rubber trim around the shell, reminiscent of classic luxury automobiles.
• French Bordeaux luxury lambskin leather with an anti-bacterial brushed “wool-touch” comfort lining.
• Each helmet is delivered in a bright red presentation box.

Safety

• Outer shell in reinforced carbon fibre and fibreglass, balancing high stability with low weight.
• Lightweight construction helps reduce fatigue on longer rides.
• The result is a helmet that stays light on the head while maintaining robust structural performance.

Superior comfort

• Double D-ring fastening for secure, precise adjustment.
• The inner leather and lining soften and mould to the rider over time.
• Comfort is tuned for long rides, not just short city hops.
