Expert breakdown: Ergodyne Skullerz LOKI-AF Anti-Fog Convertible Safety Glasses/Goggles Review (2026) →
The Ergodyne Skullerz LOKI-AF is the anti-fog variant of the convertible LOKI safety eyewear system, adding anti-fog lens coating to the glasses-to-goggles convertible design. Rated ANSI Z87.1+ and MIL-PRF-32432 ballistic fragmentation Class 1, it addresses the fogging limitation of the standard LOKI in sealed goggle configuration. Available in five variants — Clear and Smoke lenses in Black and Matte Gray frames, plus Indoor/Outdoor Black — at comparable pricing.
Construction and Materials
The LOKI-AF shares the same frame and conversion system as the standard LOKI — removable rubber temple arms, included elastic strap, and foam gasket insert — with the addition of an anti-fog lens coating. The anti-fog treatment maintains lens clarity in the sealed goggle configuration, where the foam gasket traps body heat that causes rapid fogging on untreated lenses. Frame options include Black (56003, 56083, 56033) and Matte Gray (56103, 56133), providing tonal variety beyond the standard LOKI's single Black frame. Variants: Clear/Black (56003), Clear/Matte Gray (56103), Indoor/Outdoor/Black (56083), Smoke/Black (56033), Smoke/Matte Gray (56133).
Compliance
ANSI Z87.1+ for high-velocity and high-mass impact. MIL-PRF-32432 ballistic fragmentation Class 1. CSA Z94.3 for Canadian site compliance. Identical compliance certifications to the standard LOKI.
Performance Assessment
The anti-fog coating is the critical practical improvement over the standard LOKI for workers who use the goggle configuration regularly. The sealed foam gasket traps exhaled warm air against the lens surface — without anti-fog treatment, fogging occurs within minutes of beginning physical work in goggle mode. The LOKI-AF's coating extends the usable time in sealed configuration before lens clarity is impacted, particularly relevant for grinding, cutting, and masonry operations where sustained goggle use is required.
The Matte Gray frame option provides an alternative to Black for facilities with specific frame color preferences or for workers who prefer a different aesthetic. Performance across all variants is otherwise identical — the frame color is the only differentiation between same-lens-tint variants.
Strengths
- Anti-fog coating resolves the primary limitation of the standard LOKI in sealed goggle configuration
- Converts between open safety glasses and sealed goggle with elastic strap and foam gasket
- MIL-PRF-32432 ballistic fragmentation Class 1 alongside ANSI Z87.1+
- Two frame colors (Black and Matte Gray) provide more variety than the standard LOKI
- Five variants covering Clear, Indoor/Outdoor, and Smoke lens applications
Limitations
- Anti-fog coating provides improved but not indefinite fog resistance in high-exertion goggle use — prolonged sealing in extreme humidity may still cause fogging
- Foam seal is a dust barrier only; not rated for chemical splash
Recommended Use Cases
Construction, manufacturing, utilities, grinding, masonry, cutting, and demolition applications where the worker alternates between open safety glasses and sealed goggle configuration within the same shift, and where anti-fog performance is required in goggle mode. Also suitable for law enforcement and range safety applications requiring the MIL-PRF-32432 ballistic rating.
Verdict
The LOKI-AF is the preferred variant for workers who plan to use the goggle configuration for extended periods during high-exertion or high-humidity operations. Workers who will primarily use the glasses configuration with only occasional goggle mode should consider the standard LOKI at likely lower cost.
Frequently Asked Questions
- What is the difference between LOKI and LOKI-AF?
- The LOKI-AF adds anti-fog lens coating to the convertible system. In sealed goggle configuration, the LOKI-AF maintains lens clarity significantly longer than the untreated LOKI. If you use the goggle mode regularly or during high-exertion work, LOKI-AF is the better choice.
- Does the anti-fog coating work in glasses mode as well?
- Yes. The anti-fog coating is active in both glasses and goggle configurations. In open temple-arm mode, the coating prevents the fogging that can occur during temperature transitions and high-exertion outdoor work.
- What ANSI rating does the LOKI-AF carry?
- ANSI Z87.1+ for high-velocity and high-mass impact. MIL-PRF-32432 ballistic fragmentation Class 1. CSA Z94.3.
- What is the difference between Black and Matte Gray frame options?
- Both are the same frame in different colors. Protective performance, conversion system, and ANSI/ballistic certifications are identical. The Matte Gray provides a muted color option for workers or facilities with specific frame appearance preferences.
- Can the LOKI-AF be used for chemical splash protection?
- No. The foam gasket provides airborne dust/debris barrier protection. Chemical splash protection requires dedicated indirect-vent chemical goggles with a liquid-tight seal and appropriate ANSI Z87.1 splash rating.

expected better... and better i received
UPDATE::without me even asking, and to my happy surprise, ergodyne took it upon themselves and sent me another pair. they happen to be the color i had originally wanted, so bonus. i did have to come back here and put in writing that i have been wearing the replacement pair for a few weeks now, and these do not have the issue i was having with the first pair. the anti-fog lenses are wonderful, and a welcome change from the hazy, obstructed view that most glasses of any sort give when they fog up. and being in a time where face coverings are required, which exasperates the issue, i can wear my mask properly, and comfortably while still using my eye protection without ant complications.i like the foam gasket that is included, but i haven't yet switched the ear pieces out for the goggle strap. nice that it's an option though.so, the first pair i had must have had a defect, and the company recognized that, and had enough confidence in their product to make it right. i don't find that kind of backing of goods very often.i've had these for about a week, and the anti-fog coating is already not holding up on the right side lens. this was a big part of the reason I chose to purchase these safety glasses. with having to wear a face covering while at work, it makes doing my job nearly impossible, and dangerous to be looking through foggy lenses. i got rid of the last 2 pair of safety glasses I had for that reason. after reading the description for these, and how it boasted that the anti-fog was indelible , made to last for the life of the glasses, which can handle taking a direct blast of buckshot apparently... i thought i found what i needed. i guess not. i can see fine out the one side, and a blury mess on the other. and after the first pair i ordered, which the seller didn't inform me until nearly a week after they were to have arrived that they were on back order, I ordered a second pair because I needed eye protection that would allow me to still have clear vision. well, looks like my hunt will continue on until I finally find the safety glasses that truly won't fog up on me, and last more than a week or so. i don't have money to just keep throwing away on false claims.

Overall VERY happy and a great glasses, with adjustment.
I bought this pair, the Loki, and the Valkyrie. I have a very narrow face so I had to have my optometrist adjust them for me. Now they wrap around and fit me perfectly. Also, the seal on the foam insert has a pretty decent seal against dust and air bourn particles now that it fits well. This will definitely fit a large man or someone with a fat head without any adjusting! But anyway, now that I have them adjusted I wore them the first day for 4 hours straight mowing and weed eating in the HUMID summer heat of NC and even though I was sweating a lot, they did not fog up one bit! I tried the Valkyrie's on for about an hour while weed eating and during that time I ALSO wore a full face shield with ear-pro combo. While I was wearing the face shield my breath was being trapped and causing so much humidity that the shield was fogging a little and sweat and condensation was dripping down my face and over my glasses. Even with all that, the glasses still did not fog up!The only "CON" that I could find with these glasses so far are the temple pieces behind your ears really start to hurt WHEN YOU WEAR EAR MUFF STYLE EAR PROTECTION. This is no fault of the glasses however, just something to be aware of. Just wear ear plugs instead or take off the temples and wear the strap goggle style.

Very comfortable if they're all you wear on your face
These are very comfortable using either the arms or the elastic strap. I have a clear & wide field of view. The foam cushion around the lens should help lessen any impact. The elastic strap is easy to adjust and is holding up well (elastic will degrade over time.) Two points to consider:- The description (when I purchased it) said "anti-fog". They're not anti-fog. Not even close. In moderate humidity and/or high temps, they will fog up over time.- They do not fit properly when I wear my RZ Mask. They probably won't fit when wearing respirators. They may fit when wearing cloth dust masks (I tend to not use those.) Your mileage may vary.

Not what I expected
They are comfortable and are good value for the money. But the fit for my head wasn't right and they looked a bit goofy on me. That being said they are of decent quality and the lenses offer decent vision.

Good for pandemic
I work in a medium traffic area that not everyone wears their masks properly that passes by. I see too many nostrils and there is a guy that works nearby that wears his mask like he is at a nudist colony. So, after having a pair of these as sunglasses (polorized) I figured it was a no brainer to get another pair that was clear with antifog. The strap helps a lot to keep a seal around the eyes and my vision is not impaired at all. I do some bending over and lifting so without the strap they try to fall off. The antifog holds up after the glasses are at room temperature. Going into a hot or cold room they will have moisture on the inside lense but after acclimation it isn't a problem. If the room you are in gets cold or hot there will not be any moisture. As far as comfort it does take some getting use to. The rubber padding can make marks on you if you have the strap on too tight but they are, of course, not permanent. If you use the arms they don't make the mark but the seal itsn't exactly complete either. Stay Safe! A little discomfort until you get used to it is better than getting the virus.

Meets expectations thus far.
shipped and arrived fast. Pretty comfortable so far and look good.. solidly made it seems. No issues with fogging so far but only brought them to the outdoor range. Not sure when I will take them to the indoor range where I have constant fog issues with other glasses... assume they perform well unless I update it in the coming weeks.Only issue I would say is that even though I have a large head they are a little loose. When I look/lean forward they do almost slide off which is a little annoying. I do wish some of the other lens colors came with anti fog besides just clear and smoke but oh well.

Not great ....
These safety glasses/goggles definitely aren't anti fog. They fog up easily, regardless of how tight/loose you keep the strap. The lenses also scratch easily. Since there's no adjustment points, I find them to be an uncomfortable fit.

Fully Satisfied!
I have never been happier to finally get a product that meets the description!! They came with the strap but make sure you pick the right pair that says with the strap! Fit snug and comfortable. Can’t wait to see how they work when I’m cycling this weekend doing 20plus miles a hour😎

Good protection and the convertible design is useful
The anti-fog feature works at first, but comfort could be better for long periods of wear. Overall, a decent product with a few drawbacks.

Incredibly Practical
Incredibly practical. I enjoy how tactical these look. I initially got these glasses to wear during helicopter operations for my job. I hated using the regular eye pro because once the rotor wash hit, kicking up debris and dirt and grass from the landing zone, stuff would always get into my eyes. I got these modifiable glasses because I was drawn to the rubber insert that acts as a seal for the peripherals of your eyes. Also, the ability to swap the sides with a strap made it incredibly practical for keeping these, now goggles, snug to my eyes whenever the helicopter was landing. Overall, they were really comfortable and practical. Like all glasses, they fogged up, but I have yet to find a single pair of eye pro that doesn't.
