ESS® Crossbow® 3LS 740-0387 is a professional ballistic protective eyewear kit with three interchangeable lenses designed for military, tactical, shooting, training and professional use. Crossbow® combines the Tri-Tech Fit™ comfort system, high-precision ESSOPTICS™, ClearZone™ FlowCoat technology and the DedBolt™ Lens Lock quick-change lens system.

The model is part of the modular ESS® Cross-Series™ platform, allowing Crossbow® components to be combined with compatible ESS® Crosshair™ and Suppressor™ components. The 3LS kit includes three lenses — Clear, Smoke Gray and Hi-Def Yellow — allowing the eyewear to be adapted to different lighting conditions.

Tri-Tech Fit™ — Comfortable and Stable Fit

The Tri-Tech Fit™ frame is designed to provide a secure fit while minimizing uncomfortable pressure points. The temple design helps distribute pressure more evenly and provides comfort during extended wear.

This construction is particularly important for protective eyewear that may be worn for extended periods during shooting practice, duty assignments or other active professional tasks.

3LS — Three Interchangeable Lenses for Different Lighting Conditions

Part number 740-0387 is the Crossbow® 3LS — Three Lens System configuration. It includes three interchangeable lenses:

• Clear — 90% VLT: a clear lens for indoor environments, low-light conditions and nighttime use;
• Smoke Gray — 15% VLT: a tinted lens for bright daylight and sunny conditions;
• Hi-Def Yellow — 85% VLT: a high-contrast yellow lens for conditions where enhanced visual contrast is desirable.

The ability to change lenses allows a single Crossbow® system to be used at different times of day and under varying levels of ambient light.

ClearZone™ FlowCoat — Anti-Fog and Scratch Protection

Crossbow® lenses feature ClearZone™ FlowCoat technology. The coating is designed to reduce fogging on the inside of the lens while improving scratch resistance on the outside surface.

This helps maintain a clear field of view for longer during physical activity, temperature changes and extended periods of wear.

ESSOPTICS™ — Optical Precision Without Unwanted Distortion

ESSOPTICS™ technology is designed to provide high optical precision. It helps minimize unwanted image distortion so that the shape, contours and position of objects appear as natural and accurate as possible.

This is particularly important for shooting and professional protective eyewear, where the user needs to accurately perceive the surrounding environment, distances and the position of objects.

DedBolt™ Lens Lock — Quick Lens Changes and Secure Retention

The lens is attached to the frame using the DedBolt™ Lens Lock system. The mechanism allows the installed lens to be quickly released for replacement and then securely locks the new lens into the frame.

This allows the user to switch between Clear, Smoke Gray and Hi-Def Yellow lenses according to current lighting conditions without needing separate protective eyewear.

100% UVA and UVB Protection

ESS® lenses provide 100% protection against UVA and UVB radiation. This allows Crossbow® eyewear to be used for extended periods outdoors and in intense sunlight.

Cross-Series™ — ESS® Modular Eyewear Platform

Crossbow® is part of the ESS® Cross-Series™ platform. Crossbow® components are compatible and interchangeable with corresponding components from:

• ESS® Crosshair™;
• ESS® Suppressor™.

For example, a Crosshair™ frame can be upgraded with premium Crossbow® anti-fog lenses, while the ultra-thin Suppressor™ frame can be used for improved compatibility with full-size hearing protection or communications equipment. This allows a single protective eyewear platform to be adapted to different tasks and equipment configurations.

Prescription Lens Compatibility

ESS® Crossbow® supports the ESS® U-Rx Insert system. It allows prescription lenses to be installed inside the protective eyewear system for users who require vision correction.

The prescription insert and prescription lenses are sold separately.

ESS® Crossbow® Ballistic and Protective Standards

For the current Crossbow® 740-0387 version, the manufacturer states compliance with the following standards:

• U.S. MIL-PRF-32432A;
• ANSI Z87.1-2015;
• CE EN166;
• U.S. Federal OSHA.

These are the standards that should be used in the current product description instead of the older MIL-PRF-31013 specification listed in the previous version of the product information.

Important APEL Information
