Description

G4 Helmet Replacement Liner

The G4 Liner delivers a smooth, snug fit with breathable padding that keeps you comfortable from take‑off to landing. Designed for durability and all‑day wear, it’s the perfect refresh for your G4 helmet.
The G4 Liner is engineered for consistent fit, impact‑comfort performance, and long‑term durability. Its multi‑density foam structure maintains shape under repeated load cycles, while the moisture‑wicking fabric layer improves airflow and reduces heat retention during extended use. The liner integrates cleanly with the G4 shell geometry, ensuring stable contact points and reduced internal movement throughout freefall and canopy flight. A practical replacement component that restores helmet comfort and maintains optimal in‑helmet pressure distribution.
