MCR BearKat BK3 Safety Glasses — ANSI Z87.1+ Soft Nose Bridge, Anti-Fog

The MCR Safety BearKat BK3 is the comfort-and-fog-control member of MCR's BearKat line — ANSI/ISEA Z87.1+ high-impact, keeping the classic BearKat wraparound but adding a soft, cushioned nose bridge that eases pressure during full-shift wear. It's also the only BearKat with UV Anti-Fog on both Clear and Gray, across eight tint variants. If nose-bridge soreness or fogging is your problem, the BK3 is the BearKat that solves it.

Why the MCR BearKat BK3 is the comfort pick

Two small things make safety glasses miserable over a full shift: a rigid nose piece that leaves a sore mark, and a lens that fogs the moment you exert. The BK3 addresses both — a cushioned nose bridge that spreads the contact pressure, and UV Anti-Fog on both Clear and Gray so you can run fog control indoors or out. It's the same classic BearKat wrap and Z87.1+ rating, tuned for all-day wearability. Our full BearKat BK3 review rates it 4.5/5, and the safety glasses buyer's guide covers how comfort features affect all-day compliance.

What the listing documents

From the published specs: ANSI/ISEA Z87.1+ high-impact rating; a classic wraparound polycarbonate frame with a soft (cushioned) nose bridge; Duramass and UV Anti-Fog coatings, with anti-fog on both Clear and Gray; eight tints — Clear, Gray, Light Blue, Silver Mirror, Blue Mirror, and I/O Mirror; not OTG; base model BK310. As mcr safety bearkat eyewear, the BK3's cushion makes it one of the few soft nose bridge safety glasses in the economy tier, and with dual AF it's a genuine anti fog wraparound safety glasses option.

Choosing your BK3 variant

Match the tint to the light and the coating to your humidity: Clear or Clear Anti-Fog from the clear-lens collection for indoor work, Gray or Gray Anti-Fog for outdoor glare (see the clear-vs-smoke lens guide), and I/O Mirror for shifting light from the I/O collection. Since the BK3 is the anti-fog BearKat, its AF variants pair with the anti-fog guide and the anti-fog collection.

Where the BK3 sits in the BearKat family and MCR line

The BearKat line splits by fit and feature: the BearKat BK1 is the base economy frame with the widest tints including Amber, the BearKat BK2 is the slim low-profile option with no anti-fog, and this BK3 adds the cushioned nose bridge and dual anti-fog. For a wider premium wraparound see the Klondike KD7; the foam-lined Swagger SR1 and economy Checklite CL1 fill out MCR's value tiers.

Where it fits by wearer and crew orders

The cushioned bridge and fog control suit long shifts and humid trades — 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.
