What Makes the iQ Series Different
The iQ Series® was engineered around wearer comfort, using lightweight inherent fabrics with mechanical stretch and a patented sleeve pleat that allows full-range arm movement. Nomex® Comfort, Ten Cate Evolv™, and Westex G2™ fiber blends deliver inherent flame resistance — built into the fiber, not a chemical finish — while moisture management and breathability make these garments suitable for daily all-day wear in demanding field conditions.
iQ Series Collections — Comfort, Mobility & Endurance
The iQ Series organizes into three collections. Comfort woven shirts and pants use a refined hand-feel fabric for office-adjacent field roles. Mobility coveralls feature the patented sleeve pleat and stretch panels for confined-space work. Endurance work shirts use heavier woven fabrics for abrasion-resistant field use. All three share NFPA 2112 certification and arc ratings covering CAT 1 and CAT 2. Women’s iQ Series fits are also available.
What does iQ Series mean? +
iQ Series® is Bulwark FR’s line of comfort-focused flame resistant workwear, engineered with lightweight inherent fabrics, mechanical stretch, and the patented iQ sleeve pleat for unrestricted arm movement. The ‘iQ’ stands for intelligent design — FR protection built for all-day comfort in demanding field conditions.
What arc rating does the Bulwark FR iQ Series carry? +
The iQ Series carries arc ratings from 6.1 to 10 cal/cm², covering NFPA 70E arc-flash PPE categories CAT 1 (4–7.9 cal/cm²) and CAT 2 (8–24.9 cal/cm²). The specific arc rating required for your task is determined by your employer’s arc-flash risk assessment.
Is the Bulwark FR iQ Series NFPA 2112 certified? +
Yes. iQ Series garments in this collection are certified to NFPA 2112 for flash-fire protection. They use inherent fiber technologies — Nomex® Comfort, Ten Cate Evolv™, and Westex G2™ — so flame resistance is built into the fiber and does not wash out when laundered per manufacturer care instructions.
What iQ Series styles are available? +
The iQ Series spans shirts (lightweight and midweight woven, comfort woven, endurance), pants (lightweight and midweight work pants, cargo), and coveralls (iQ Mobility and Premium iQ). Men’s and women’s fits are available. Browse FR Shirts, FR Pants, and FR Coveralls to see all iQ Series options.
How does the iQ Series sleeve pleat work? +
The patented iQ Series® sleeve pleat is a fabric fold engineered into the back of the sleeve that opens when the wearer raises their arm, providing full-range motion without stretching the garment body. This is especially valuable for linemen and technicians working overhead or in confined spaces where restricted arm movement creates fatigue.
Can I wear iQ Series garments as daily workwear? +
Yes. The iQ Series is specifically designed for daily all-day wear, with lightweight fabrics and moisture management that make FR protection comfortable enough for full shift use. Workers who have switched from standard workwear to FR often find iQ Series garments the most comfortable choice for everyday compliance.
Garment selection should always be based on a qualified arc flash risk assessment or flash fire hazard analysis conducted by a qualified person per NFPA 70E and NFPA 2112 requirements. ATPV and cal/cm² ratings describe the garment’s tested performance — proper garment selection, fit, care, and use within an employer’s complete PPE program determine real-world protection. Copperstone Workwear supplies these garments as an authorized Bulwark FR distributor; all certifications and performance ratings are those of the manufacturer.
