Helmet replacement liner GIRO Synthe inner padding, size S (51–55 cm), black

Replacement inner padding for the GIRO Synthe helmet in size S (51–55 cm), black. This liner is designed to fit the Synthe helmet shell and restore the helmet's original fit, cushioning and sweat-management properties. It provides a comfortable contact surface between the head and the helmet, helping maintain proper fit and stability during cycling. The padding is intended for maintenance, comfort restoration or when the original liner is worn or damaged.

Advantages

The GIRO Synthe inner padding offers renewed cushioning and improved fit without altering the helmet shell. Made to match the Synthe helmet's internal contours, the liner improves sweat absorption and helps control moisture against the head. Replacing the liner can extend the usable life of the helmet, maintain hygiene and restore the original wearing comfort. The black color provides a neutral appearance that integrates with the helmet interior.

How to use

Remove the old liner from the helmet by detaching any hook-and-loop fasteners or clips holding it in place. Align the replacement liner with the helmet's internal attachment points and press firmly to secure it, ensuring all edges sit flush against the shell. Check that the liner does not obstruct adjustment mechanisms and that the helmet retains proper fit and stability once worn. For best results, wear the helmet and verify comfort and positioning before riding.

Usage recommendations

Inspect the liner periodically for wear, compression or odor; replace when the padding no longer provides adequate cushioning or moisture control. Clean the liner according to manufacturer's guidance—typically hand wash with mild detergent and air dry—to maintain hygiene and prolong service life. Always ensure the liner is compatible with your helmet model and size before installation.
