Ergodyne Skullerz LOKI Convertible Safety Glasses / Goggles — ANSI Z87.1+

The Ergodyne Skullerz LOKI is a convertible safety eyewear system that transitions between wraparound safety glasses and sealed goggles through an included elastic strap and foam gasket kit. Rated ANSI Z87.1+ and MIL-PRF-32432 ballistic fragmentation Class 1, the LOKI provides versatile protection across general safety glass applications and dust/debris environments in a single pair. Available in Clear, Indoor/Outdoor, Blue Mirror, and Smoke lenses with Black frame at $14.99–$27.99.

Construction and Materials

The LOKI features a wraparound polycarbonate lens in a co-polymer frame with removable rubber temple arms. An included foam gasket insert fits around the frame perimeter to form a partial seal against dust and airborne debris when worn in glasses configuration. The included elastic strap replaces the temple arms for goggle configuration, providing head-retention for high-movement applications. The foam insert is flame-resistant and hypoallergenic closed-cell foam. All lens options provide 99.9% UV protection. Variants include Clear (56000), Indoor/Outdoor (56080), Blue Mirror (56092), and Smoke (56030).

Compliance

ANSI Z87.1+ for high-velocity and high-mass impact. MIL-PRF-32432 ballistic fragmentation Class 1 — this military standard requires the lens to withstand a steel projectile at 660 ft/s (201 m/s), approximately 4x the velocity required by ANSI Z87.1+. The ballistic certification applies to the lens across all lens tints. CSA Z94.3 certification for Canadian sites.

Performance Assessment

The LOKI's convertibility serves workers who need a sealed dust/debris barrier for certain tasks — grinding, cutting, masonry, demolition — while preferring open temple arms for general site mobility and ventilation during other tasks. Rather than carrying two separate pairs, the LOKI provides both configurations with the same lens and frame. The foam gasket's sealed configuration is effective for airborne dust but is not a certified chemical splash goggle.

The MIL-PRF-32432 ballistic rating extends the LOKI's applicability to law enforcement, range safety, and security applications alongside standard construction and industrial use. For anti-fog performance in the goggle configuration, the LOKI-AF variant adds anti-fog coating to address the fogging that sealed goggles create by trapping body heat.

Strengths

• Converts between safety glasses and sealed goggles — one pair serves both dust-protection and open-temple applications
• MIL-PRF-32432 ballistic fragmentation Class 1 certification exceeds ANSI Z87.1+ impact standard
• Foam gasket reduces airborne dust and debris ingress in glasses configuration
• Removable elastic strap for secure goggle-mode retention during high-movement work
• CSA Z94.3 certification for Canadian site compliance
• Four lens options cover clear indoor, variable-light, and outdoor bright conditions

Limitations

• No anti-fog treatment — the sealed goggle configuration can cause significant fogging; consider the LOKI-AF for anti-fog goggle applications
• Foam seal is a dust barrier only — not a certified chemical splash or liquid-tight goggle

Recommended Use Cases

Construction, manufacturing, utilities, grinding, cutting, masonry, demolition, and law enforcement/range safety applications requiring ANSI Z87.1+ or ballistic-rated eyewear. The convertibility is particularly suited to trades that alternate between high-debris operations and general site mobility within the same shift.

Verdict

The Ergodyne Skullerz LOKI is a well-executed convertible safety glass for workers who need both open and sealed configurations. For anti-fog performance in goggle mode, the LOKI-AF is the preferred variant. For non-convertible anti-fog safety glasses at lower cost, the Ergodyne Skullerz ODIN-AF provides comparable ANSI Z87.1+ performance.

Frequently Asked Questions

How does the LOKI convert from glasses to goggles?

Remove the rubber temple arms from the frame side ports and attach the included elastic head strap. Install the foam gasket insert around the frame perimeter for a sealed dust barrier. The conversion takes approximately 30 seconds and requires no tools.

What is MIL-PRF-32432 ballistic certification?

MIL-PRF-32432 is the US military lens ballistic performance standard. It requires the lens to withstand a steel projectile at 660 ft/s — approximately 4x the velocity of ANSI Z87.1+'s high-velocity impact test. This makes the LOKI suitable for law enforcement, military training, and range safety applications where ballistic fragment protection is required.

Does the foam gasket make the LOKI suitable for chemical splash protection?

No. The foam gasket provides airborne dust and debris barrier protection. It is not a certified chemical splash or liquid-tight goggle. Chemical splash applications require dedicated indirect-vent chemical goggles with ANSI Z87.1 splash rating.

Why should I choose the LOKI-AF over the standard LOKI?

In sealed goggle configuration, the foam gasket traps body heat and causes significant fogging on standard lenses. The LOKI-AF's anti-fog coating mitigates this, maintaining lens clarity during extended goggle-mode wear. If you plan to use the goggle configuration regularly, the LOKI-AF is the better choice.

What ANSI rating does the LOKI carry?

ANSI Z87.1+ for high-velocity and high-mass impact. Additionally certified to MIL-PRF-32432 ballistic fragmentation Class 1 and CSA Z94.3.
