Built for the toughest high-threat jobs, the ESAPI (Enhanced Small Arms Protective Insert) Series offers six tailored models—covering full torso to targeted defense—to meet global military, law enforcement, and high-risk security needs. All pair monolithic SiC ceramic, lightweight UHMWPE, and anti-fragment tech for uncompromised IV-level protection.
The ESAPI Series isn’t just a set of plates—it’s a flexible protection solution. With six models ranging from large full-torso shields to compact spot guards, every plate meets NIJ 0101.06 Level IV standards on its own, no extra backing layers needed. The core formula stays consistent: monolithic silicon carbide ceramic (stops armor-piercing rounds), UHMWPE (keeps weight down), and Anti-BFS material (blocks fragment harm). Designed to work with bulletproof vests, they balance tough defense with all-day comfort—perfect for frontline combat, counter-terror raids, or high-value asset protection worldwide.
- Monolithic Silicon Carbide Ceramic: Hard enough to shatter high-velocity armor-piercing (AP) and incendiary (API) rounds. It soaks up the extreme kinetic energy of IV-level threats—like 7.62x63mm M2 AP—without cracking, a must for life-or-death scenarios. 
- UHMWPE: Cuts weight dramatically (from 0.82kg to 3.75kg, depending on size) while adding flexibility. You can wear these plates for 6+ hour missions—combat patrols, tactical drills—without fatigue, and they hold up to rough movement. 
- Anti-BFS Material: Traps bullet fragments and leftover impact force. No more secondary injuries from ceramic shards or projectile debris, even if you take multiple hits. 
Every plate has a 600D black Oxford outer layer—water-resistant (no seepage in rain), flame-retardant (safe near sparks), and scratch-proof. It shields the core from dust, moisture, and wear during transport, storage, or tactical use, so the plates last longer, even in harsh conditions.
- Multi Curve (MS-4E Series): Mirrors your torso’s natural shape (chest/back), so they fit snugly in standard ESAPI carriers. No pressure points during all-day wear, and you can bend, run, or climb freely—perfect for full-torso defense. 
- Single Curve (S-4T Series): Optimized for small, targeted areas (neck, shoulders, side torso). They add protection without bulk, ideal for patrols or escort missions where full plates are overkill. 
These plates aren’t just lab-certified—they’ve been put through tough tests in labs worldwide, following NIJ 0101.06 protocols at 15 meters:
- Multi-Shot Resistance: Handles several hits from common rifle rounds without penetration: 7.62x51mm M80 NATO, 7.62x39mm AK47 MSC, 5.56x45mm SS109/M193. 
- High-Threat Stopping Power: Reliably blocks one shot of armor-piercing/incendiary rounds: 7.62x63mm M2 AP (M1 Garand’s heavy-duty round) and 7.62x54R API (sniper/machine gun ammo). 
This testing proves they perform consistently, no matter the threat or environment.
- NIJ 0101.06 Level IV: All models meet the strictest standard for personal ballistic defense, stopping AP/API rounds that Level III/IIIA gear can’t handle. 
- Vest Compatibility: Pair them with your existing bulletproof vest to upgrade protection—no need to buy new full gear, saving time and money. 
- No Weak Spots: Ceramic coverage nearly matches plate size (e.g., 280x356mm for the 285x361mm model), so every inch of the protected area is equally tough. 
Each model is tailored to specific jobs:
- Large Multi-Curve (MS-4E285361SA / MS-4E265342SA): Full-torso defense for military frontline troops (urban warfare, counter-insurgency) and SWAT counter-terror teams. 
- Medium Multi-Curve (MS-4E246323SA / MS-4E227303SA): Balanced coverage for security teams (VIP protection) and government contractors (infrastructure work in conflict zones). 
- Compact Single-Curve (S-4T154205SA / S-4T150150SA): Targeted defense for patrol officers (shoulder/side torso) and private security (escort missions in moderate-threat areas). 
Backed by a 5-year manufacturer’s warranty, covering defects in materials and craftsmanship. This guarantee reflects confidence in the series’ durability—even under heavy tactical use—so global users can trust it for years.
