Frequently Asked Questions
Q: What's the difference between SGE 400/3 and SGE 400/3BB? A: The SGE 400/3 has a silicone face seal. The SGE 400/3BB has a butyl rubber face seal, which provides superior resistance to chemical warfare agents (nerve agents, mustard gas) and meets stricter CBRN requirements. The 400/3BB is also slightly lighter. If you need maximum chemical protection, consider the 400/3BB version in our NBC Protective Kit.
Q: Does this include a filter? A: Yes. One sealed NBC filter is included. We recommend stocking spare filters for extended use or multiple threats.
Q: What does the filter protect against? A: The included NBC filter protects against chemical warfare agents (sarin, mustard gas, VX), biological threats (bacteria, viruses, spores), radioactive particulates, industrial chemicals, tear gas (CS/CN), and toxic vapors.
Q: How long does the filter last? A: Sealed and stored properly, filters have approximately a 10-year shelf life. Once opened or exposed to contaminants, replace after use or per manufacturer guidance based on exposure level.
Q: Why does this mask have 3 filter ports? A: The left, right, and center ports let you position the filter where it's most comfortable and least obstructive. Shooters typically mount on the opposite side of their dominant eye for unobstructed rifle shouldering.
Q: Can I use other 40mm NATO filters with this mask? A: Yes. The SGE 400/3 accepts any 40mm NATO threaded filter (EN148-1 / DIN 3183), including the NBC-77 SOF and other CBRN filters.
Q: Is this mask reusable? A: Yes. The mask itself is designed for repeated use with proper maintenance. Filters should be replaced after exposure to contaminants.
Q: What certifications does this mask have? A: EN136:1998 certified. EU PPE Category III per Regulation 2016/425.

I am very happy with this office chair. It was easy to assemble, feels sturdy, and is very comfortable to sit in for long periods of time.

Great Chair! Worth the Price!
Color: Sky Blue, Size: Pack of 1
LOVE my new desk chair! I got the Sky Blue which is a really pretty blue in person. I work from home in tech, and had been getting constant headaches no matter what position I was in. I finally decided to invest in a better desk chair, and I'm SO glad I did! It's much more supportive and comfortable. I really like that I can flip the arms up or down, and the height is easy to adjust. Also, because I can flip the arms up, I can keep the chair out of the way when I'm not working by putting it right up against the desk. Very much worth the price! Assembly was simply and quick. Not even 30 minutes. Also, when I had a question about the chair, their support team was quick to respond and very helpful. Highly recommend!

Great quality chair, regardless of price.
Color: Black+white, Size: Pack of 1, Color: Black+white, Size: Pack of 1
Great quality chair, regardless of the price, period. So well packaged that it took almost as long to unwrap as assemble. Assembly was easy (loved the Allen wrench with sturdy handle). I am 6'2" and the fit and height adjustments work well for my height. Comfort is personal, so I like the semi-firmness of the seat. While the chair is constructed of heavy gauge plastic the base is solid metal with enamel finish: I love the look. The arm rests line up perfectly to my computer keyboard. I expect many, many years of service.

Great Value for a Comfortable Home Office Chair
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I’ve been using this chair for a couple of days now, and honestly, it’s been a solid upgrade from my old one. I work from home most days, so comfort matters a lot—and this chair delivers better than I expected for the price.
The first thing I noticed was the lumbar support. It’s actually adjustable and makes a noticeable difference, especially if you tend to sit for long stretches. My lower back used to get sore after a few hours, but that hasn’t really been an issue since switching to this chair. The mesh back is also a nice touch—it keeps things breathable, which I didn’t think I’d care about until I had it.
Assembly was pretty straightforward. Took me maybe 20–25 minutes without any frustration. Everything lined up well, and the instructions were clear enough.
In terms of comfort, the seat is firm but not hard. It doesn’t feel like one of those super plush chairs, but I actually prefer that because it feels more supportive over time. The reclining feature is smooth, and I like that you can lean back a bit when you need a break.
Overall, I’d say this is a great value for a home office setup. If you want something ergonomic and comfortable without spending a fortune, this chair is definitely worth considering.
