Maximum Protection Featuring Boron Carbide (B₄C) and UHMWPE
Bronyx Ultimate (Size Large) is a premium individual ballistic protection solution that combines increased coverage area with incredibly low weight. Utilizing Boron Carbide (B₄C) — one of the hardest materials on Earth—these plates provide Class 5 protection while remaining significantly lighter than standard ceramic (Alumina) or steel alternatives.
Key Advantages of the Large Model
-
Expanded Protection Area: The 26x33 cm dimensions provide an 8 dm2 protection area, ideal for users with a chest circumference between 111 and 118 cm.
-
Extreme Durability (B₄C): The Boron Carbide ceramic strike face effectively shatters armor-piercing (AP) bullet cores, minimizing the risk of penetration.
-
Anatomical Shooter’s Cut: The specialized corner cuts combined with a Multi-curved (dual-plane) design allow the plate to fit snugly against the body, ensuring unrestricted arm movement and a comfortable weapon stock weld.
-
Four-Layer Energy Absorption System:
-
External damping (Closed-cell polyethylene foam).
-
Primary protection layer (Boron Carbide ceramic).
-
Ballistic backing (UHMWPE).
-
Trauma-reducing layer to mitigate Back Face Deformation (BFD).

Ballistic Resistance and Protection
These plates are engineered to stop heavy calibers and high-velocity projectiles:
-
7.62 x 39 mm API (Armor-Piercing Incendiary) — velocity 750±15 m/s.
-
7.62 x 54 mm LPS (Light Steel Core) — velocity 850±15 m/s.
Minimal Back Face Deformation:
Thanks to the stabilizing UHMWPE layers, the deformation depth upon an LPS impact is only 12 mm, which is significantly below critical safety thresholds, preventing severe internal blunt force trauma.
Materials and Construction
-
Ceramic Layer: Boron Carbide (B₄C) — delivers the highest level of hardness at the lowest possible mass.
-
Ballistic Core: Ultra-High-Molecular-Weight Polyethylene (UHMWPE) — captures fragments and dissipates kinetic energy.
-
Protective Cover: Durable Oxford fabric protects the plate from UV radiation, moisture, and mechanical abrasion in harsh field conditions.
Bronyx Ultimate Large is the choice for professionals who value the balance between large-scale protection and high mobility. This set is ideal for extended wear in active combat zones.
