MCR Klondike OG2 OTG Safety Glasses — ANSI Z87.1+ Over-the-Glasses, Hi-Vis Option

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.

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.
