GameBreaker Stealth Helmet Liner - All Purpose Helmet Insert

GameBreaker Stealth Helmet Liner – Advanced Protection for Any Helmet

Revolutionary Impact Protection with D3O® Technology

Upgrade your helmet with the GameBreaker Stealth Helmet Liner, powered by advanced D3O® smart molecule technology. This military-grade impact protection material flows freely under normal conditions but instantly locks together on impact to absorb and disperse force, reducing the risk of injury. The greater the impact, the greater the protection—all while maintaining flexibility and comfort.

Key Features:

• Universal Fit – One size fits all, designed to fit comfortably in helmets, caps, or beanies
• Full Head Coverage – Added protection for the rear, front, and sides
• Ventilated for Airflow – Keeps you cool and comfortable during play
• No Hard Plastic or Metal – A soft, flexible design that won’t interfere with helmet performance
• Compatible with All Sports – Ideal for football, hockey, motocross, snowmobiling, and more

Simple Installation & Custom Fit

Easily customize your Stealth Helmet Liner to fit any helmet without modifying or damaging your gear. Simply trim off any excess D3O® using household scissors or a utility knife—no special tools required.

How to Install:

1. Place the Stealth Helmet Liner inside your helmet with the orange side facing out.
2. Adjust for comfort, then trace a line along any overhanging areas using a permanent marker.
3. Remove the liner and trim off excess material along your markings.
4. Reinsert with the printed comfort liner facing out, and you're ready to go!
