## Long description

The GIRO Aerohead Ultimate helmet liner in black, size M (55–59 cm) 2017 is an inner padding component created to restore or enhance the fit and comfort of compatible Giro Aerohead helmets. Designed as a replacement or spare part, the liner provides cushioning and moisture management to help maintain a stable, comfortable fit during cycling sessions, time trials and races. The liner’s shape and materials match the Aerohead shell geometry to ensure correct positioning when installed in a compatible helmet.
Advantages
This helmet liner offers targeted cushioning that reduces pressure points and improves long‑term comfort. The fabric and foam combination absorbs sweat and helps manage moisture to reduce slippage. As a replacement part, it restores original fit and can extend the usable life of the helmet by renewing interior surfaces. The neutral black color and size M fit a wide range of riders who use Giro Aerohead shells sized 55–59 cm.
Suitable for

How to use
Remove the old liner from the helmet shell according to the helmet manufacturer’s instructions and check the shell’s attachment points for wear. Align the replacement liner inside the Aerohead shell so that its edges and mounting points match the internal contours, then press gently to secure into place. Ensure the liner sits flat without folds and test the helmet on the head to confirm correct positioning and comfort before riding.
Usage recommendations
For hygiene and performance, wash the liner by hand using mild detergent and cold water, then air dry away from direct heat. Inspect attachment points regularly and replace the liner if foam degradation or detachment occurs. Confirm compatibility with your Giro Aerohead shell before purchase to ensure proper fit.
