The MCR Safety Klondike OG2 OTG solves the eyeglass-wearer's problem without a prescription order: an ANSI/ISEA Z87.1+ over-the-glasses frame that fits over most prescription eyeglasses, on MCR's larger Klondike frame. Six variants add hi-vis frame options and MAX6 Anti-Fog or Dual Coat coatings — the upgrades the entry-level OG1 OTG skips — for Rx wearers who need impact protection now.

Why the MCR Klondike OG2 OTG fits eyeglass wearers best
Prescription safety glasses cost money and time; an OTG frame gives the same Z87.1+ impact protection over the glasses you already own, instantly and universally. The OG2 puts that on MCR's larger Klondike frame — more room for the Rx frame underneath — and adds the two things the entry OTG lacks: hi-vis frame options for high-visibility sites, and MAX6 anti-fog for the fogging that OTG frames are prone to. Our full OG2 OTG review rates it 4.4/5, and the safety glasses buyer's guide covers when OTG beats prescription lenses.
Safety first: the OG2 OTG is 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 OTG goggles or a face shield per your hazard assessment. OTG fit is critical: verify it seats and closes over your specific prescription frame, since a frame too large to fit leaves gaps that defeat the seal. And OTG frames fog more, so choose the MAX6 anti-fog variant for indoor or humid work. Choose eyewear against measured hazards using the when-do-you-need-safety-glasses guide.
What the listing documents
From the published specs: ANSI/ISEA Z87.1+ high-impact rating; an over-the-glasses (OTG) Klondike frame that fits over most prescription frames; polycarbonate lenses; 6 variants — Clear and Gray, in standard and hi-vis frames, across MAX6 Anti-Fog and Dual Coat coatings; model OG210PF. As mcr safety klondike eyewear, the OG2 is the family's over the glasses safety glasses option, and its hi vis otg safety glasses variants suit high-visibility sites the standard frame can't serve.
Choosing your OG2 OTG variant
Match the build to the site: MAX6 Anti-Fog for indoor, humid, or mask-heavy work (OTG fogs more — see the anti-fog guide and anti-fog collection), Gray for outdoor glare over clear Rx lenses (the clear-vs-smoke guide covers tint), and the hi-vis frame where visibility is required. Compare the full OTG field in the over-the-glasses collection, including the Uvex Astro OTG.
Where the OG2 sits in the Klondike family
The OG2 is the OTG member of the Klondike line — the rest are standard-fit: the KD7 economy workhorse, the KD5 two-variant stock, the KD3 bifocal, the KD7R ratchet-temple, and the premium KD1. Its OTG sibling is the entry-level Law OG1 OTG. The full MCR Safety glasses collection and the best safety glasses 2026 roundup place the OG2 against other brands.
Where it fits by wearer and crew orders
OTG suits eyeglass-wearing crews and visitor programs — and for prescription wearers weighing options, the women's fit guide and small-face guide cover fit over smaller Rx frames. Where the hazard exceeds impact — splash, dust, vapor — step to a sealed OTG goggle from the 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 Klondike OG2 OTG?
An over-the-glasses (OTG) safety glass on MCR's larger Klondike frame, rated ANSI/ISEA Z87.1+ high-impact and designed to fit over most prescription eyeglasses. It comes in 6 variants across Clear and Gray tints, standard and hi-vis frames, and MAX6 Anti-Fog or Dual Coat coatings.
What does OTG (over-the-glasses) mean?
OTG frames are sized to fit over your own prescription eyeglasses, giving Z87.1+ impact protection without buying prescription safety lenses. The OG2's larger Klondike frame accommodates most Rx frames underneath.
Who should choose an OTG glass over prescription safety glasses?
Anyone who wears glasses occasionally at a jobsite, visitors and contractors who need temporary protection, or workers who don't want the cost and lead time of prescription safety lenses. OTG is the fast, universal answer for eyeglass wearers.
What are the hi-vis frame options for?
High-visibility yellow/orange frames make the eyewear (and the wearer) easier to spot in high-visibility-required environments - roadwork, warehouses, and sites where being seen matters. The hi-vis frame is an option the entry-level OG1 OTG doesn't carry.
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, worn over your glasses.
What coatings are available?
MAX6 Anti-Fog for humidity and mask fog, and Dual Coat, across the tint and frame options. OTG frames trap more warm air near the lens, so a strong anti-fog like MAX6 matters more here than on a standard glass.
OG2 OTG or the Law OG1 OTG?
The OG2 is the upgrade: the larger Klondike frame, hi-vis frame options, and MAX6/Dual Coat coatings that the entry-level Law OG1 OTG doesn't carry. If you need hi-vis or premium anti-fog over your glasses, step to the OG2.
Will it fit over any prescription frame?
It fits most standard prescription frames, but very large or wraparound Rx frames may not seat well. Check the fit over your specific glasses - an OTG that doesn't close properly leaves gaps that defeat the seal.
Is it enough, or do I need goggles?
The OG2 OTG protects against impact and debris from the front and sides. It is not a sealed goggle - it does not seal against a chemical splash hazard, fine dust, or vapor, which need sealed OTG goggles or a face shield. Match the eyewear to your hazard.
Does it fog more because it's OTG?
OTG frames sit further from the face and trap warm air between two lenses, so fogging is a bigger risk - which is why the MAX6 Anti-Fog variant is the smart default for indoor, humid, or mask-heavy OTG use.
How do I care for the lenses?
Rinse grit before wiping and use a microfiber or lens-safe cloth on both the OTG lens and your glasses underneath; harsh cleaners strip anti-fog coatings. Retire the OTG lens once scratches enter your line of sight.
