The S1 Helmet Liner is a replacement or sizing liner designed for S1 Lifer, Mini Lifer, and Mega Lifer helmet shells. This is ideal for achieving a tighter, more secure fit. Perfect for replacing worn liners or adjusting helmet comfort, it helps ensure your helmet continues to fit properly and perform at its best.
This red S1 Helmet Liner is ideal for skaters who need a slightly tighter fit in their Lifer helmet shell. At 12 mm thickness, it provides a snug, locked-in feel without compromising comfort. Great for active riders who want their helmet to stay firmly in place during tricks, falls, or extended sessions.
S1 Helmet Liners are colour-coded by thickness to make sizing simple. The red liner is Small (12 mm). If your helmet feels too loose, use a thicker liner; if too tight, go thinner.
| Liner Colour | Size | Thickness |
|---|---|---|
| Grey | XS | 14 mm |
| Red | S | 12 mm |
| Gold | M | 10 mm |
| Black | L | 8 mm |
| Green | XL | 6 mm |
| Blue | XXL | 4 mm |
| Purple | XXXL | 2 mm |
Fit Guidance: The red 12 mm liner is best if your helmet feels slightly loose with thinner liners. For more adjustment flexibility, consider keeping a set of multiple colours.
No. The red liner indicates Small size (12 mm thickness) but it fits into any S1 Lifer series helmet shell. You choose the liner based on fit preference, not helmet shell size.
No. The shell provides the main protection. Liners adjust fit and comfort. As long as the liner is seated correctly, your helmet remains safe.
Yes. Many skaters mix a thicker liner in the front and a thinner one in the back (or vice versa) for a truly custom fit.
Simply remove the existing liner from the Velcro inside the helmet and press in the new one. No tools required.
