Bulwark® STL3 Women’s Flex Knit Henley FR Long-Sleeve Shirt

The STL3 carries an Arc Thermal Performance Value (ATPV) of 8.3 cal/cm² and is rated Arc Category 2 (CAT 2). It is also NFPA 2112 compliant, making it suitable for oil and gas, refinery, and petrochemical environments that require certified FR and arc-rated apparel.

The shirt is constructed from a 6.75 oz. Electric Hazard Protection, Flame Resistant fabric blended at 93% Cotton / 7% Spandex Elastane. The cotton-dominant blend provides inherent flame resistance without sacrificing comfort, while the spandex component adds the stretch needed for active, physical work environments common on Gulf Coast jobsites and refineries.

The STL3 is designed exclusively for women, featuring a classic/regular fit tailored to a woman's body. Curved flatlock seams further reinforce the gender-specific construction, providing a structured shape and reducing irritation during extended wear in industrial environments.
