Accessories – S1 Helmets Australia

Use liners and replacement parts to refine a fit—not to force the wrong shell.

Accessories are most useful once the helmet shell range is already correct. Use the product range first, then use liner products to replace worn parts or fine-tune a snug, stable fit within the Mini Lifer, standard Lifer, or Mega Lifer family.

Start with the problem you are trying to solve.

Fine-tune the current fit

If the shell range is correct but the helmet needs a closer, more stable feel, start by checking the sizing liner options.

Replace worn liners

Use replacement liners when existing liner pieces need refreshing. Check the relevant product page to confirm the current options.

Unsure about the shell?

If the helmet still rocks, sits incorrectly, or feels wrong after checking the shell, revisit the helmet fit before buying extra accessories.

Good fit check:

the helmet should sit level, cover the forehead, and move with the head rather than sliding independently. Liners are there to refine a correct shell range, not to make an unsuitable shell fit.
