Mestel Safety SGE 400/3 BB CBRN Gas Mask – Italian-Made Full-Face Respirator with Butyl Rubber Seal
The Mestel SGE 400/3 BB is the CBRN-rated version of one of the most respected gas masks in the prepper community — built with a butyl rubber face seal to deliver true chemical, biological, radiological, and nuclear protection. Made in Italy by Mestel Safety, this mask balances professional-grade performance with a price point that won't break the bank.
Why It's a Top Pick for Preppers:
- Butyl rubber face seal — full CBRN compliance against blister agents (Mustard/HD), nerve agents (Sarin/VX), and other CWAs
- Triple filter ports (3x NATO 40mm / EN 148-1) — front, left, and right
- Run 1, 2, or 3 filters — adapt to environment & breathing needs
- Polycarbonate ballistic visor with chemical-resistant coating
- 92% visible light transfer — clear, distortion-free vision
- Soft inner orinasal cup prevents CO2 buildup, reduces fogging
- 6-point quick-release harness — fast, secure donning
- EN 136:1998 certified
The 3-Filter Advantage: Most gas masks have 1 or 2 filter ports. The SGE 400/3 BB has three — giving you serious flexibility:
- Single filter (right or left side): clean cheek weld for shooting
- Front filter: balanced breathing for general use
- Dual or triple filters: extended runtime + maximum airflow in heavy CBRN environments
Compatibility:
- Works with any NATO 40mm CBRN-rated filter (EN 148-1 / DIN 3183)
- Filters from Mestel, MIRA, Avon, 3M, and other major brands
- Compatible with optional Mestel hood, drinking system, and speech diaphragm (sold separately)
