Constructed with mission-critical durability, the CS-100 features a lightweight silicone Gas Mask for all-day comfort under intense conditions. The shatter-resistant polycarbonate lens offers unparalleled protection while maintaining a wide field of vision 89% effective and 91% overlapped to ensure full situational awareness in high-stakes operations. The 6-point adjustable harness guarantees a tactical-ready fit, while the two 40mm NATO threads ensure compatibility with standard filters for operational flexibility.

When it comes to performance, the CS-100 is built for the heat of battle. Its low breathing resistance as little as 0.25 mbar at 30 L/min airflow and minimal inward leakage (<0.03%) mean you stay focused and mission-ready, even under the harshest conditions. Whether advancing through tear gas or holding the line, this gas mask ensures peak efficiency and ease of use.

Paired with the N-B-1 Defense Canister, the CS-100 becomes an unstoppable force in riot control scenarios. The N-B-1 provides elite-grade filtration with an A2B2E2K2P3 protection level, shielding against organic vapors, acid gases, sulfur dioxide, ammonia, and particulate hazards. Tested against battlefield conditions, this canister offers superior gas resistance, delivering critical defense during exposure to agents like chlorine (25 minutes at 15 mg/L) or hydrogen sulfide (45 minutes at 7.1 mg/L). With <0.03% filter penetration and breathing resistance of just 1.1 hPa at 30 L/min, the N-B-1 is engineered for tactical superiority.

Key Features:

  1. Designed for Military Use: Built for riot control and chemical defense.
  2. Lightweight and Durable: Silicone face seal, shatterproof polycarbonate lens, and weighs only 485g.
  3. Wide Field of Vision: 89% effective and 91% overlapped for superior situational awareness.
  4. 6-Point Adjustable Harness: Universal fit with a secure seal.
  5. Low Breathing Resistance: Easy to breathe even under heavy use, with minimal inward leakage (<0.03%).
  6. 40mm NATO Compatibility: Works with standard 40mm NATO (STANAG 4155 / EN148-1) Canisters.
  7. Advanced Filtration (N-B-1 Canister): A2B2E2K2P3-rated protection against gases, chemicals, and particulates.
