The MCR Safety Swagger SR4 is the wide-coverage sport-wrap in MCR's Swagger line — ANSI/ISEA Z87.1+ high-impact, with a wider lens geometry that wraps further around the temple than the SR1 or SR2. That extra wrap reduces the side-entry angle for airborne particles, sparks, and UV without a full goggle, and the SR4 adds MAX6 anti-fog plus a Black Mirror MAX36 polarized option for high-glare outdoor work.

Why the MCR Swagger SR4 covers more
The weak spot of a narrow sport frame is the side gap — sparks and wind-blown chips find the opening between lens and temple. The SR4 closes it: a wider lens that wraps further around the face, cutting the side-entry angle for particles, sparks, and UV, without the bulk and fog of a full goggle. Add MAX6 anti-fog and a Black Mirror polarized option and it's the Swagger for the toughest coverage needs. Our full Swagger SR4 review rates it 4.5/5, and the safety glasses buyer's guide covers coverage vs. bulk tradeoffs.
Safety first: the SR4's wider wrap helps against side-flying debris, but it is still impact-and-debris protection, not a sealed goggle — it is not rated against a chemical splash hazard, fine airborne dust, or vapor, which require sealed goggles or a face shield per your hazard assessment. For grinding and cutting, pair it with a face shield where the task calls for one. Choose eyewear against measured hazards with the when-do-you-need-safety-glasses guide.
What the listing documents
From the published specs: ANSI/ISEA Z87.1+ high-impact rating; a wide-coverage sport wraparound polycarbonate frame; tints in Clear, Gray, Fire Mirror, Blue Diamond Mirror, and Black Mirror polarized; coatings in Standard, MAX6 Anti-Fog, and MAX36 Polarized Anti-Fog; not OTG; base model SR44R. As mcr safety swagger eyewear, the SR4 is the coverage-focused member — genuine wide coverage safety glasses that also offer a true polarized safety glasses variant.
Choosing your SR4 variant
Match the lens to the task: Clear from the clear-lens collection for indoor work, Gray for outdoor glare (see the clear-vs-smoke lens guide), and the Black Mirror polarized for reflective, high-glare conditions from the polarized collection — the polarized-vs-non-polarized guide explains when it's worth it. For humid or steam-prone work, the MAX6 variants pair with the anti-fog collection.
Where the SR4 sits in the Swagger family
The Swagger line splits by fit and lens: the Swagger SR1 is the foundational frame with the widest tints, the Swagger SR2 is the slim polarized option, the Swagger SR3 is the matte no-frills two-tint, and this SR4 adds the widest peripheral coverage. The Swagger SR5 and Swagger UD1 round out the series. Browse the full MCR Safety glasses collection, and the best safety glasses 2026 roundup places the line against other brands.
Where it fits by job and crew orders
The wide wrap suits grinding, cutting, and outdoor trades with side-flying debris — the construction and manufacturing guides rank frames by task, and smaller-faced wearers should check the small-face guide and women's fit guide. Where the hazard exceeds impact — splash, dust, vapor — step to a sealed goggle from the safety goggles collection or the broader eye protection collection.

Reading the Z87 marking, and what it does not cover
Protective eyewear in the US is built to ANSI/ISEA Z87.1, and OSHA 1910.133 requires eye protection that meets it. The marking on the frame is the specification, and the important distinction is a single character: Z87 is basic impact, Z87+ is high impact — tested with a quarter-inch steel ball at 150 ft/s for spectacles. If the work throws anything, Z87+ is the line.
The suffixes narrow it further: D3 is splash and droplet, D4 dust, D5 fine dust. These matter because a spectacle cannot earn D3 — droplet protection needs a sealed goggle. Safety glasses are impact protection, not chemical splash protection, however wraparound the lens looks, and substituting one for the other is a common and consequential error.
A face shield is also secondary protection under 1910.133: it is worn over primary eye protection, never instead of it. And tint is not shade — a dark lens without a stated IR/UV shade number offers no rated protection against radiant energy.
Frequently asked questions
What is the MCR Safety Swagger SR4?
The wide-coverage sport-wrap in MCR's Swagger line, rated ANSI/ISEA Z87.1+ high-impact. Its wider lens geometry wraps further around the temple than the SR1 or SR2, reducing the side-entry angle for airborne particles, sparks, and UV - with MAX6 anti-fog and a Black Mirror polarized option.
How is the SR4 different from the SR1 and SR2?
Coverage. The SR4 addresses the one gap in the SR1 and SR2 - peripheral protection - with a wider lens that wraps further around the temple. If side-flying debris or sparks are a concern, the SR4's geometry closes more of the side-entry angle than the narrower frames.
What does the wider wrap actually do?
It reduces the angle at which particles, sparks, and UV can reach the eye from the side, without the bulk of a full goggle. For grinding, cutting, and outdoor work with wind-blown debris, more wrap means fewer side gaps.
Is it ANSI Z87.1+ rated?
Yes - it carries the ANSI/ISEA Z87.1+ high-impact rating (the '+' marks passing the high-velocity and high-mass impact tests), so it meets the requirement for most industrial eye hazards.
What is MAX6 anti-fog?
MAX6 is MCR's anti-fog coating, offered on the SR4's Clear and Gray variants (SR410PF, SR422PF). It keeps the lens clear in steam-prone or humid environments, so the glasses stay on the face instead of pushed up.
Does the SR4 have a polarized option?
Yes - the Black Mirror MAX36 variant (SR417BZDC) is polarized with anti-fog, aimed at marine, driving, and high-glare outdoor work where reflected glare is the problem. Our polarized guide covers when it's worth it.
What tints does the SR4 come in?
Clear, Gray, Fire Mirror, Blue Diamond Mirror, and the Black Mirror polarized - across Standard, MAX6 Anti-Fog, and MAX36 Polarized Anti-Fog coatings. Match the tint to your light and the coating to your humidity and glare.
Is it over-the-glasses (OTG)?
No - the SR4 is not an OTG frame. Prescription-glasses wearers should look at MCR's OTG models like the Law OG1 or Klondike OG2, which fit over your own glasses.
Is it enough, or do I need goggles?
The SR4 gives more side coverage than a narrow frame, but it still does not seal against a chemical splash hazard, fine dust, or vapor - those need sealed goggles or a face shield. For high-velocity side hazards it helps; for sealing hazards, step up. Match the eyewear to your hazard assessment.
Is the SR4 good for grinding and cutting?
Its wider wrap suits grinding and cutting where sparks and chips come from angles, paired with the Z87.1+ high-impact rating. Confirm it against your task's specific hazard level, and add a face shield where required.
How do I care for the lenses?
Rinse grit before wiping and use a microfiber or lens-safe cloth; harsh cleaners strip the anti-fog, mirror, and polarized coatings. Retire a lens once scratches enter your line of sight - a scratched safety lens no longer protects fully.
How do I order for a crew?
Quantity purchasing runs through a free Amazon Business account - volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations. The bulk-ordering walkthrough is linked in our site footer.

Buy a different brand of glasses these are horrible
Came with micro scratches all over the lenses that didn't wipe off with cleaner. They are comfortable and frames seem like good quality but I'm upset the lenses are already scratched. After 4 days of use i went to clean them with MCR Safety brand wipes and it left a permanent scuff. They already have a deep scratch on a lenses. They fog up terribly absolutely don't buy these. These are worse then the one piece cheap glasses work provides.
