12CAL Arc Protection That Moves With You

The Portwest FR404 Bizflame 88/12 Stretch FR Trousers deliver serious protection without the stiff, restrictive feel of traditional flame-resistant workwear. Built for electricians, utility workers, and anyone facing arc flash hazards, these trousers combine certified multi-norm protection with stretch fabric that actually lets you move. The slim fit design stays form-fitting without restricting your range of motion—crucial when you're working in tight spaces or need to move quickly.

Key Features:

• Bizflame 88/12 Stretch Fabric: The clever mix of 86% cotton, 12% nylon, and 2% elastane at 350g weight gives you natural flame resistance with the flexibility you need. The garment wash treatment creates an exceptionally soft feel—none of that cardboard-stiff texture you get with cheaper FR gear.
  
• Protection Against Multiple Heat Hazards: Guards against radiant, convective, and contact heat. Certified to EN ISO 11612 (A1+A2, B1, C1, F1) for comprehensive thermal protection in hazardous environments.
  
• Flexi-Fit Technology: Added freedom of movement where you need it most. The stretch fabric works with your body instead of against it—bend, crouch, climb without feeling restricted.
  
• Adjustable Hem Design: Converts from regular to long leg length. No need to order multiple sizes or deal with trousers that bunch up inside your boots.
  
• Practical Storage: Four pockets plus two back patch pockets. Enough room for tools, phone, and essentials without overloading your belt.
  
• Professional Appearance: Available in Navy. The slim fit looks sharp while maintaining all the protective properties you need for oil and gas, chemical processing, welding operations, and electrical utilities.
