S1 Lifer Helmet Replacement Sizing Liners

S1 Lifer Helmet Replacement Liners

Replacement sizing liners for compatible S1 Lifer-series helmets. Use these liners to refresh worn padding or fine-tune helmet fit within the appropriate shell size.

Compatibility

• S1 Mini Lifer
• S1 Lifer
• S1 Mega Lifer

Select the liner size that corresponds to your helmet shell and required fit. Measure your head and confirm compatibility before ordering.

Replacement liners should fit securely inside the helmet and should not be used to make an incompatible helmet shell fit.
