Ultralite 3-A Plate Backers — UDPE Soft Armor Trauma Backers
Build-to-order estimate: 30 days ± 2 weeks depending on inventory levels. Check with us for your order’s current ETA.
Ultralite 3-A Plate Backers are high-performance UDPE (ultra-high-molecular-weight polyethylene) soft armor panels engineered to sit directly behind a hard rifle plate. They reduce backface deformation, capture spall and fragmentation, and add NIJ Level III-A / HG2 handgun protection to any plate pocket.
Why a plate backer?
- Backface signature reduction — dissipates the load a rifle round transfers through a hard plate.
- Spall and fragmentation capture — arrests jacket fragments and ceramic spall behind the strike face.
- Edge-to-edge III-A coverage — full handgun protection across the panel, including areas where ceramic strike-face coverage is smaller than the plate cut.
- Ultra-light — 7 mm thick, 1.1 lb per square foot.
