MCR Swagger SR4 Safety Glasses — ANSI Z87.1+ Wide-Coverage Sport Wrap, Polarized

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.

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.
