**Note: Our helmets currently available in one size only (Unisize), so please take a couple of moments to ensure it is the right size for you before purchasing.**
Find a measuring tape and wrap around your head just above your eyebrows.
Use our video fit guide & size chart below to help you get the right measurement.
Why do you only have one size?
We've just launched the LID brand and currently have one size available, Unisize (55cm - 58cm). This captures the average head sizes for all genders. We are currently developing a full size range for riders across the world, which we hope to have available in the coming months.
The 4-notch adjustable fit system on the sides of our helmet and velcro adjustment at the rear allow the fit of the helmet to be further tailored to the rider's head. Additionally, our multi-piece design enables the helmet to auto-adjust to different head shapes, whilst providing excellent ventilation.
