The Ops Core Retrofit Combat Liner offers the most technologically advanced suspension systems available. This technology was originally developed for the US SOCOM and other Tier 1 first responders. The suspension system (padding) is a rate and temperature sensitive material that conforms to wearer’s unique head shape.

These materials provide unparalleled comfort, fit, and stability. The padding is covered in a heat and moisture wicking anti-microbial fabric. It is designed to draw perspiration away from the head and will actually cool the wearer through this evaporative process.

Both Independent and DoD testing have shown 4DT suspension systems provide superior blunt impact as well as ballistic performance over current OEM and aftermarket suspension system product offerings. See Marine Corps SMART-TE ACH test results on reverse: 20 companies provided product samples and white papers. 5 products were selected to advance. 4DT was 1 of 2 that advanced to the final gate and out performed all other product offerings.
