The Israeli 4A1 is a genuine full-face CBRN gas mask developed for Israeli civilian defense. It provides reliable protection against chemical, biological, radiological, and nuclear (CBRN) airborne threats. It comes complete with a sealed 40mm NATO NBC filter and a hydration tube straw attachment, ready to use out of the box.
Trusted by thousands of buyers worldwide with 500+ verified reviews, this is authentic Israeli surplus equipment - not a replica, not a training prop. The 4A1 is the same mask distributed to Israeli civilians for national emergency preparedness.
Have a beard? The 4A1 requires a clean face seal and will not seal properly over facial hair. For bearded users, we recommend the Israeli Sapphire CBRN PAPR Hood for Bearded Men - a powered hood respirator that provides full CBRN protection without requiring a face seal.
Want easier breathing during extended wear? The 4A1 is fully compatible with the ONYX 45 PAPR blower, which delivers 45 LPM of powered, filtered air directly into the mask, eliminating breathing resistance and is especially recommended for older adults or anyone with reduced lung capacity. See our complete powered kit for a ready-to-use bundle.
Keep a spare sealed filter in your kit. Browse our full range of 40mm NATO NBC filters - available in single, 2-pack, 3-pack, and 4-pack options.

Everything I expected was in the box. I checked the threads, visor and straps, then did a short fit test at home. Everything was fine.
The mask seems well made, but I am still struggling to get the rear straps comfortable around the back of my head. I am keeping it, although the fit has not fully convinced me yet.
Protection gear is never going to be pleasant, but this mask feels heavier than I anticipated. The view is good, and that is definitely its strongest point for me. Comfort is only average, though, and the extra weight is noticeable enough that the overall experience feels mixed rather than fully positive.
Second mask for our household. I chose the same model again because everyone already knows how to adjust it.
The fit became much better once I loosened everything and tightened the straps from the bottom up. After that, the seal felt even around my face.

I bought this after trying an older surplus mask that made me feel boxed in. This one gives me a much wider view, and once I had the straps adjusted it stopped demanding my attention. We practiced putting it on twice, marked the strap positions, and then stored it with our emergency gear.
Happy with the hardware. I preferred moving everything from the supplied storage box into my own soft bag.
I like the mask, especially the visor. There was a noticeable rubber smell when I first opened it, but that faded after I aired it out.
Visibility is strong and the fit feels secure. My only real complaint is the strap tabs; I would prefer them a little larger when my hands are cold.
The filter went on smoothly and the straps did not twist while I was fitting the mask. That made the first practice less frustrating.
Good mask, just a little bulky.
Surprisingly comfortable.
Feels like proper equipment, not costume gear. That mattered to me.
I expected something clumsy because it is a full-face mask. In practice it is quite comfortable, and the field of view is much less restricted than I had imagined.
The first adjustment was fiddly for me. Once I marked the strap positions, putting the mask on became much quicker and more repeatable.
Good field of view. I can look down and around without feeling as if I am staring through two small circles.
The mask itself is excellent. My only surprise was how much bulk the setup gains once the filter is attached, so it takes more room than I anticipated.
Happy I bought it.
Comfortable enough to practice with and sturdy enough that I am happy to store it long term.
Solid kit and no issue with the mask. I just wish the printed instructions had larger diagrams.
My old mask always pressed awkwardly on the bridge of my nose. This one sits differently and feels better even after ten minutes.
The first fitting took a little patience because I tightened one side too much. Once I corrected that, the mask sat properly and the rest of the adjustment was straightforward.
Schnelle Lieferung, wie beschrieben.
Great mask, Thanks

Fantastic mask, everything is as described. Mask, Drinking tube with an unused filter all of which are in good condition. The whole kit looks like it came straight from distribution which you don't often see with these masks. Seal is airtight and based on the stamps and markings this is the real deal and not a knockoff, to add I have a fake I got from a "Tactical dealer" side by side this one blows it out of the water. If you want something that will actually protect you, GET IT.
Amazing seller. Value was great and the item was exactly as described, if not better. Will definitely buy again.
The kit includes the 4A1 full-face mask, one factory-sealed 40mm threaded filter, and a hydration straw for the mask’s drinking connection. Confirm the current included-items list before ordering.
No. The product is listed as authentic Israeli civil-defense equipment. Condition and included components are shown on the product page.
The mask uses an EN 148-1 / Rd40 40mm threaded port. STANAG 4155 is commonly referenced for NATO interoperability; thread compatibility is not a filter or protection rating.
Service life depends on the exact filter, contaminant, concentration, humidity, airflow, and other conditions. Follow the filter manufacturer’s instructions and never use the unopened shelf-life date as an operating-time promise.
Yes. Facial hair, eyewear temples, face shape, damage, or incorrect adjustment can interfere with the seal. Inspect and fit the mask according to its instructions.
Keep the mask clean, dry, and protected from sunlight, heat, chemicals, and deformation. Leave the filter sealed until needed and inspect the mask, straps, valves, and package integrity regularly.

Factory seal intact, canister clean, no marks. Exactly what I wanted for storage.

Would order again.

Packed it with my camera gear and practiced putting it on quickly. After a couple of tries, the sequence felt natural.
