Bulwark® STL2 Men’s Flex Knit Henley FR Long-Sleeve Shirt

The Bulwark STL2 carries an Arc Thermal Performance Value (ATPV) of 8.3 cal/cm², qualifying it as an Arc Rating Category 2 garment. This makes it suitable for electrical maintenance and oil and gas worksites where CAT 2 arc-rated PPE is required by the site's electrical hazard risk assessment.

Yes, the STL2 is NFPA 2112 compliant, meaning the fabric meets the standard's requirements for flame-resistant materials intended to protect against industrial flash fire exposures. Workers in oil and gas, petrochemical, and refinery environments where NFPA 2112 compliance is mandated by site PPE programs can wear this garment with confidence.

The STL2 is constructed from a 6.75 oz. (230 g/m²) flame-resistant jersey knit used for both the body and contrast panels, providing a lightweight feel compared to heavier FR wovens. The flex knit construction stretches with your movements, and curved flatlock seams reduce friction points, making it a practical choice for physically demanding work across Gulf Coast and Texas oilfield environments.

The STL2 is available in six color options identified by the following lot codes: STL2BK (Black), STL2CH (Charcoal), STL2KH (Khaki), STL2LB (Light Blue), STL2NV (Navy), and STL2RD (Red). This range allows workers and safety managers to align garment selection with site-specific color-coding or personal preference while maintaining full FR and arc-rated compliance.

The STL2 can function as a primary FR layer in environments where its 8.3 cal/cm² ATPV and NFPA 2112 compliance meet the site's hazard risk requirements. However, workers should always refer to their site-specific PPE program and job hazard analysis, as some tasks may require additional arc-rated layers to achieve higher levels of protection.
