CM-6M® Tactical Gas Mask (CBRN)
A panoramic, impact-rated visor enhances situational awareness, while the hypoallergenic inner mask reduces fogging and CO₂ buildup during extended use. Dual filter ports allow left- or right-side configuration, improving compatibility with weapon systems, radios, and other mission equipment. An integrated hydration system enables safe drinking without breaking the mask seal, supporting endurance in prolonged operations or emergency scenarios.

CBRN RESPIRATORY PROTECTION
Professional-grade protection without the gatekeeping. CBRN gas masks for civilians since 2018.
MIRA Safety was founded by Roman Zrazhevskiy and Tanya Mironova in 2018 — born out of Roman's own experiences with 9/11 and Hurricane Sandy and the realization that civilians had effectively no access to military-grade respiratory protection. Their flagship CM-6M gas mask launched in 2018 (and was later featured in Christopher Nolan's TENET). The company partners with European defense contractors to bring CBRN-rated masks, filters, and protective equipment to professionals, preppers, and families — including a full line of children's protective equipment. Their philosophy: "When crisis strikes, you can't rely on anyone but yourself."

Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
What does CBRN cover?
Chemical, Biological, Radiological, and Nuclear airborne hazards. Protection depends on pairing the mask with an appropriate certified filter and on adequate oxygen being present. The mask alone is only half the system.
Can I use optics or a rifle with it?
The CM-7M and CM-8M are built for it. Tapered profiles and recessed lenses allow a natural cheek weld and correct eye relief with red dots, magnified optics, and night vision. The panoramic CM-6M and CM-I01 trade some of that for a wider field of view.
How do I get a proper seal?
The mask has to sit against clean, dry skin, and correct sizing matters. Facial hair along the sealing surface will break the seal and compromise protection. Run the fit-check procedure in the manufacturer's instructions before you rely on any respirator.
Does a gas mask supply oxygen?
No. A filter respirator cleans the air passing through it but creates no oxygen. It must never be used in an oxygen-deficient atmosphere, a confined space, or against an unidentified hazard. Those situations require supplied-air or self-contained breathing apparatus.
How long does shipping take?
Most in-stock orders are processed within 1 to 3 business days, not counting weekends and federal holidays. Special-order, dealer-direct, custom, and LYNX Survival Systems orders can take longer. Lead times shown on product pages are estimates, not guarantees.
Typical carrier transit after that: Economy 5 to 7 business days, Expedited 2 to 3, Overnight 1. These are carrier estimates, not guarantees. Some items, such as lithium batteries, aerosols, and safety matches, may be limited to ground shipping.
Free Economy shipping on qualifying orders over $150 to the contiguous US, on eligible products. Oversized, heavy, freight, hazardous-material, dealer-direct, custom-built, and special-order items may be excluded. Oversized and freight items, such as rooftop tents, recovery equipment, and Pro Eagle products, may carry extra shipping charges. If extra charges apply, we'll let you know before the order ships.
Some items ship directly from the manufacturer or a supplier partner on their own schedule, so an order can arrive in more than one package with more than one tracking number. Full details: Shipping Policy.
What’s your return policy?
You have 30 days from receiving your order to request a return on eligible items. Email info@stayreadyoutdoors.com with your order number, the item, and the reason, and wait for return authorization before you ship anything back. Returns sent without authorization may be refused.
Items must come back in like-new condition: unused, unmodified, unworn, unwashed, and free of odors, dirt, stains, pet hair, and damage, with all original packaging, manuals, accessories, and tags, plus proof of purchase.
For standard parcel items, you pay return shipping unless the return is due to our error, shipping damage, or a verified defect. If we provide a prepaid label, its cost may be deducted from your refund. For oversized, freight, dealer-direct, and special-order items, you pay return shipping unless the item arrived damaged, defective, or incorrect. Original shipping charges aren't refunded. Some items may carry a restocking fee of up to 15%, and we'll tell you during authorization.
Some items are fulfilled by third-party suppliers and follow that supplier's return policy, so eligibility, refund timing, return shipping, and restocking fees may differ.
Approved refunds go to your original payment method. Allow up to 10 business days after approval, and your bank may take longer to post it. Full details: Return & Refund Policy.
What can’t I return?
These can't be returned or refunded, except where the law requires it:
- Engraved, personalized, customized, and built-to-order products, and special-order products obtained specifically for you
- LYNX Survival Systems survival kits, custom IFAKs, and custom medical kits
- Agency, government, organizational, and contract-built orders
- Gift cards, and sale or clearance items marked final sale
- Food, drink, and other perishable products, including emergency food
- Personal care, hygiene, and beauty products
- Hazardous materials, and flammable liquids or gases
- Opened or used medical products
- Opened water treatment or purification products with broken factory seals
- Anything marked non-returnable on its product page
For built-to-order, custom, and special-order items, exceptions may be made only for verified manufacturing defects, shipping damage, or fulfillment errors. For food and drink, replacements may be issued only for verified manufacturing defects or shipping damage reported within 5 days of delivery, with photos.
Not sure whether an item qualifies? Email info@stayreadyoutdoors.com before you order.
Do you ship outside the contiguous US?
Alaska, Hawaii, Puerto Rico, Guam, and other U.S. territories aren't eligible for free shipping, and extra freight charges may apply. If your order needs a shipping quote, we'll contact you before it ships. If you decline the quote, the order may be canceled and refunded. APO/FPO addresses are also excluded from free shipping.
International shipping is available on select products and destinations, and some products may be restricted from international shipping. You're responsible for import duties, taxes, customs fees, brokerage fees, and meeting your country's import rules.
Full details: Shipping Policy.
My package arrived damaged. What now?
Inspect your order when it arrives. If anything is damaged, defective, or wrong, email info@stayreadyoutdoors.com within 7 days of delivery (5 days for food and drink) with your order number, a short description, and photos of the item and the packaging.
You don't pay return shipping on items that arrived damaged or wrong, or with a verified defect. Some items fulfilled by third-party suppliers follow that supplier's policy instead. Reporting after 7 days may limit our ability to pursue a claim with the carrier, and while we may help with a carrier claim, approval is up to the carrier.
Package lost or never arrived? Contact us within 7 days of the expected delivery date. For freight deliveries, inspect the shipment before you sign and note any visible damage on the carrier's delivery receipt.
Can I talk to a human before buying?
Yes. Call (562) 294-6269, Monday to Friday, 8:00 AM to 4:00 PM Pacific time, or email info@stayreadyoutdoors.com. We reply within one business day.
We'd rather talk you out of a kit that doesn't fit your mission than sell you the wrong one.
Do you offer a military/first-responder discount?
Yes. Current and former U.S. military, military spouses and dependents, and first responders, including law enforcement, fire, and EMS, can save up to 10% on most of our products through GovX ID.
Verify on our GovX discount page and you'll get a single-use code to enter at checkout. For later orders, log in with GovX ID for a new code (limit one code per day). The GovX code can't be combined with other discounts.
