TRUST Halo Helmet Pad System

Introducing Delta Three Oscar (D3O) Halo™
The World’s Lightest, Most Ventilated, Comfortable Helmet Liner to Exceed ACH Blunt Impact Requirements 

The D3O Halo (Delta Three Oscar Halo™) Helmet Liner System is the lightest, most ventilated, comfortable helmet liner to exceed ACH Blunt Impact Requirements (AR/PD 10-2).
Halo is 25% lighter, making it the lightest ACH 10fps suspension system, than the next best helmet liner on the market which means you can shed weight while reducing trauma.
Designed with the end user comfort fit in mind with 37% pure comfort foam all this without altering the 0.75" fit to guarantee the best-in-class short and long term comfort.
The comfort foam has been scientifically developed to provide a familiar plush, full coverage fit and is wrapped in premium MILSPEC anti-microbial working fabrics.


D3O Halo features 12 integrated airflow channels that help circulate the air in between the end-user's head and the helmet shell which helps to:

  • Prevent moisture accumulation
  • Prevent sweat build-up, reducing chance of sweat dripping in the user's eye
  • Maintain comfort foam at an optimal stiffness

D3O Halo's crown pad has been designed with a permanent headset band recess and strategically placed flex grooves to allow the pad to conform to the headset when used.


Halo exceeds the AR/PD 10-02 requirements by 33%, averaging <100g across all conditions in the most challenging liner-shell configurations.
Boasting the same overall impact performance as competitors in a 25% lighter weight package while offering a much more consistent behavior across impact locations/temperatures.


D3O's all new thermodynamic formulation allows the Halo liner to get stiffer at hotter temperatures than cold which counteracts the behavior of the shell material preventing failure-prone super-soft or super-stiff shell-liner impact events.
Halo shows an average of only 14g between cold and hot conditions which is a 67% improvement to any other product on market.
