## Long description

Replacement internal liners for the BELL 4 Forty / Hela Mips helmet in black, size M (55–59 cm), model year 2018. These liners restore the helmet's internal padding and fit adjustment, maintaining compatibility with the specified BELL shell and the Mips rotational protection system. Designed as direct replacements, they address worn, compressed, or removed padding to recover original comfort, hygiene and proper fit.
Advantages
These replacement liners are molded to match the original helmet interior and preserve the intended fit and retention of the BELL 4 Forty / Hela Mips. The black fabric provides a neutral appearance and easy maintenance, while the padding layers help absorb sweat and reduce pressure points. Using purpose-made liners retains the Mips interface alignment and the helmet’s designed clearance for impact management.

How to use
Remove the original liners by detaching the anchor points or Velcro tabs inside the helmet, noting the placement of each pad. Align the replacement liners with the corresponding mounting points and press firmly until secure. Ensure the Mips low-friction layer and any retention system are not obstructed and that the liner sits flush against the helmet shell. After installation, wear the helmet and make final fit adjustments using the retention dial or straps to confirm a snug, even fit across the head.
