Every fabric, garment, and layer is third-party tested and fully documented — engineered to meet and exceed the standards that keep workers safe.
High-visibility
Electric arc
Layering
Protects workers in traffic, low light, and poor sight lines. It comes down to two things: the class of apparel (how much of the body is covered) and the level of retroreflection (how visible it is in the dark).
Class 1
Lowest recognized coverage with good visibility.
Class 2
Moderate body coverage with superior visibility.
Class 3
Full coverage, visible from a great distance in poor light.
Retroreflection — visibility in the dark
Level 1
Moderate distance
Level 2
Long distance

Flame / arc apparel
Background color & testing
Fluorescent yellow
Orange
Red
Each color is tested for chromaticity, colorfastness, retroreflection, and luminance. Orange is used on most of our FR clothing — widely recognized as a hazard identifier.
A second-degree burn is possible when unprotected skin is exposed to an arc flash above 1.2 cal/cm². Arc rating (ATPV) describes how a material performs against that energy.

Most tasks require a minimum of 8 cal/cm². Protection is selected based on the incident energy of the specific task.
What we test for
Physical strength
Breaking load, tear resistance, seam slippage
Colorfastness
Shade and dimensional change after laundering
Initial flammability
Char length measured before washing
After-wash flammability
Retested to confirm lasting performance
We third-party test layers and combinations to determine the true ATPV and category of protection across the full collection — so employers know exactly what a worker's clothing provides.
Proprietary fabrics, fully tested
Because we build with our own fabrics, we can test nearly every combination in the arc-rated collection.
Tested as worn
Garments are tested in the layers they're designed to be worn in, for accurate data in hazardous situations.
True protection confirmed
Establishing the real ATPV ensures workplace safety standards are met with confidence.
