Size Guide | Fox Helmets

Use these size guides to find the correct fit before placing your order. Measurements are provided in centimetres (cm) and inches (in) where available, covering chest, waist, hips, height, and hand width depending on the product category.

For the most accurate results:

  • Use a flexible tape measure.
  • Measure directly against the body, not over bulky clothing.
  • Keep the tape level and snug, but not tight.
  • Compare your body measurements to the size chart rather than relying on your usual size.

If you are between two sizes:

  • Choose the smaller size for a closer, performance fit.
  • Choose the larger size for a more relaxed fit or for layering.

Sizing can vary slightly between product ranges and categories (e.g. MTB, casual wear, gloves, helmets). Always refer to the specific size table listed below.

If you require further clarification on fit or sizing, contact customer support before ordering.
