K9 Helm CS1-A2 Replacement Shell

CS1-A2 Replacement Shell | K9 Head Protection | Working Dog PPE

K9 Helm is the original and only tactical dog helmet built in the USA. Specifically made for dogs who engage in dangerous work, the CS1-A2 GoggleHelm from K9 Helm is the ideal choice for police K9 and military working dogs. Born to meet the needs of USSOCOM, this dog helmet features include military ballistic eye wear spec wrap-around lens, 6061 aluminum side mounting plates for detachable muzzles, a low-profile removable picatinny rail on top, and an internal Biothane retention collar as a primary means for securing when deployed.

CS1 replacement shells fit all CS1-A2 Gogglehelms made — 2023 and newer. They come with left and right side internal cheek vents and Velcro hook panels installed, and a user guide. Swapping shells involves removing 8 screw fasteners from the existing GoggleHelm: 2 at the rear, 2 on both left and right sides, and 2 on top for the picatinny rail. Installing these fasteners gently, with minimal tightening force is a must, to avoid stressing the shell. Overtightening fasteners causes stress cracks in polycarbonate plastic. Low strength threadlocker like Loctite 222 or equivalent is required. Higher strength threadlockers are strongly discouraged, as it may prevent future disassembly.

New for 2025, the CS1-A2 is made of injection molded polycarbonate, which is over 25 times more impact resistant than the previous, 3D printed model. Variant A2 meets or exceeds US military specifications for ballistic safety eye wear. Compliance to: MIL-PRF-31013 and MIL-V-43511C. Test Projectile: Chisel point, 0.15 Caliber @ 750+ FPS
