Meet Transformer. Featuring an interchangeable design, it quickly transitions from standard temples to an elastic head strap; integrated side protection works with both. Our BK-Anti-FOG+ protection keeps your vision clear. The Transformer’s rugged good looks, with a nylon and TPR frame, and black/dark gray temples, says Brass Knuckle through and through.

About the Transformer

The 8 base curve polycarbonate lens offers unobstructed field of vision and high-impact protection, while the built-in dust filter forms a seal to keep out dust and airborne particles. The filter protects workers from intense wind, sun, dirt, dust and debris, as well as high heat and humidity. Soft nylon and thermoplastic rubber (TPR) temples flex to adjust to wider facial profiles, helping to ensure these spectacles remain comfortable to wear without distorting the optics. The durable polycarbonate lens features Brass Knuckle’s BK-Anti-FOG+ coating, offering superior performance under the most demanding hot and humid conditions for a long-lasting, fog-free view.
