ESS Innerzone™ Structural Fire Goggles
The ESS Innerzone™ Structural Fire Goggles provide heat- and flame-resistant eye protection designed specifically for structural firefighting. The Innerzone series combines high-impact polycarbonate lenses, full-perimeter ventilation and filtration, anti-fog and anti-scratch lens treatments, and helmet-compatible mounting systems for demanding fireground environments.
Cascade Fire Equipment offers three current Innerzone configurations, each using the same protective goggle platform with a different helmet attachment system. Select the mounting style that best matches your structural fire helmet and face-protection setup.

INNERZONE STRUCTURAL TS
The Innerzone Structural TS uses a two-piece strap with semi-permanent mounting brackets secured to the helmet brim with thumb screws. No drilling is required. This configuration keeps the goggles attached to the helmet and allows them to be stored on the front or rear of the helmet.
INNERZONE STRUCTURAL SO
The Innerzone Structural SO uses ESS Snap-on/Snap-off™ mounting brackets. Circular strap grommets connect to low-profile helmet brackets, allowing the goggles to remain helmet-mounted or be quickly removed and stored separately. This configuration works well with face shields and flip-down eye protection.
INNERZONE STRUCTURAL FS
The Innerzone Structural FS uses a one-piece wrap-around strap secured to the helmet with two hook-and-loop tabs. The ESS Speed-Clip™ system allows quick strap adjustment, even while wearing gloves.
LENS & VENTILATION
All three current Innerzone models use a clear 2.6 mm polycarbonate lens with ESS ClearZone™ FlowCoat treatment. The exterior lens surface receives scratch-resistant protection while the interior is treated for anti-fog performance. Full-perimeter ventilation and filtration help reduce fogging while filtering airborne particles, dust, and debris.
