Butyl Rubber Face Seal — CBRN Rated, EN136:1998 Certified
This is the CBRN Rated version of the SGE 400/3 mask, which features a Butyl Rubber construction that will properly protect against Blister agents, as well as Nuclear/Radiological threats in conjunction with a proper filter.
You can find the alternate version, with a more comfortable, non CBRN-rated silicone face seal, Here.
The SGE 400/3 mask has been designed to meet military and civil defense requirements. It features three possible filter ports, allowing for comfortable aiming of a rifle, or usage of equipment. Along with glasses adapters and speech diaphragms, it can also accept a drinking tube and microphone connection, making it an ideal prolonged and specialist usage.
The entire body of the masks is made of a strong, rigid material (polycarbonate) and is therefore able to allow full protection for the face and eyes against extremely violent impacts. It replaces the rubber bodies previously employed by traditional designs to bear the weight to which the mask is subjected. Additionally, the face shield has been treated to resist exposure to aggressive substances, like mustard gas.
Due to the use of an integral load-bearing face-piece, it was possible to make the rubber face-seal much lighter, as its only function is to act as a seal. The seal is made of very soft rubber with a supple bellows type structure which allows perfect sealing and a very high degree of comfort even after very prolonged use. The straps, face-seal and stiff body of the mask together means that the effort applied by the straps is distributed evenly. Enabling the user to achieve a perfect seal without having to tighten the straps excessively and uncomfortably.

Take measurements as show below and use the chart to find the correct size:
Fit and Seal Testing
Testing the fit and seal of your respirator is important. Every face and head is unique, and what may work on one person may not work on you. Because of this, it is crucial to inspect & leak test your SGE 400/3 mask prior to use.
To check that the seal on your mask is sound, you will need to perform a negative pressure test. To do this, cover the front filter port with your hand so that no air can flow though it to your mask and inhale.
If you feel immediate pressure on your face, and your mask sucks inward on your face like air out of a bag, your seal is perfect. If this doesn't happen and/or you feel air rush in from somewhere in the mask, you have a leak somewhere in your seal that needs to be remedied.
Seal leaks can be resolved by adjusting the placement on your face, tightening the head harness, and ensuring identifying hair/ facial hair is not breaking the seal line. If none of this works, you might have to change the size of your mask.

Specs
Mestel Safety SGE 400/3BB NATO CBRN Gas Mask
This respirator/mask is the most comfortable piece of PPE I've worn. It feels extreme comfortable with long hair aswell especially for extended periods of time
It's probably the highest quality gas mask I've ever worn. Quick to put on and adjust, and very comfortable once on.
I'm familiar with M50 gasmasks from my service and some commercial half masks. The comfort is as advertised, did some pushups and other exercises with it on and didn't feel irritated. However I get more trouble with donning mask than the M50. Make sure to practice getting a reliable seal when fitting the mask, because its not as dummy proof and there's a decent margin of error. If I tighten one side too much, too little, or a little out of sequence it can make the mask not seal even with me fully tightening the top straps. Perhaps this is sizing error on my part, but I measured multiple times and seem to be in a little awkward middle spot for sizing, longish face with small head. The top buckles also like to catch my hair and do its' best to rip it from my scalp. A bit surprising since I boast a mil reg haircut. If you have long hair make sure tie it back.
I'm a small on the MSA Millennium, so I got a small one of these; it seals well, but the temple area presses in too hard. Uncomfortable, but I'm planning on getting the large for comparison. Having rubber headstraps means it will grip hair, but it's not too bad. The mask does have more FOV than the Millennium, and is comparable to my Honeywell 76008A. It has a neat little lanyard for carrying. Condition was Factory-new, even having the protective film on, lawyerspeak included. Came with a paper manual, which is slightly different to the online manual (mainly having fewer pictures). Speech diaphragm is a little buzzy, but entirely discernable. I didn't buy the corrective lens insert in time, so I cannot comment on it.
Mint condition and perfect size !
