Smaller. Lighter. Calmer at speed.
The C45 is the evolution of the G4 . A full carbon fibre shell cuts overall weight, while a new 4-shell system reduces the helmet’s volume for every head size. It sits closer and feels lighter.
Certified to XP S 72-600:2018 for skydiving and wind tunnel use, the C45 was developed with afocus on stability at speed and tested in fast, dynamic flight. As one experienced athlete put it:“It feels calmer at speed.“
Three finishes, one construction
Every C45 is full carbon fibre. Choose how you show it: Gloss Carbon (exposed weave withracing strip), Gloss White, or Matte Black.
A fit you can tune
The C45 delivers our most refined fit yet and is easier experience both putting on and taking off. The new replaceable cheek pad system lets you dial in exactly how the helmet holds you: cheekpads come in four thicknesses (8, 16, 24 and 32 mm), so you can move from the standard fit to afirmer, locked-in feel that stays secure at speed. Check the size printed on the back of yourcurrent cheek pads, then go thicker for a firmer fit or thinner for a more relaxed fit.
With 4 shell sizes covering 8 head sizes (54–62 cm), there’s a C45 right for you.

Customise your C45
Like our other full-face helmets, the C45 can be configured with your choice of visor and sideplates.
Side plates
Choose from a range of colours and styles of aluminium side plates.
Visors
- Mirrored — Blue, Purple, Green or Orange. A mirrored finish that cuts glare in bright conditions.
- Photochromic. Automatically adjusts its tint to the light. UV-reactive molecules darken the lens in bright sun and return it to clear in low light — one visor from sunrise to sunset.
- Pinlock. Fitted with a Pinlock anti-fog insert: a moisture-absorbing inner lens sealed against the visor to create an insulating air pocket — like double glazing for your visor.The most effective anti-fog solution for cold air, humidity.
