11,000mm Waterproofing That Actually Keeps You Dry

The Portwest S594 Extreme Bib & Brace doesn't mess around when it comes to weather protection. Built with 300D stretch Oxford fabric and a PU membrane, this hi-vis overtrouser delivers 11,000mm waterproofing and exceptional 50,000g/m²/24hrs breathability. That means you stay bone-dry outside and comfortable inside, even during extended shifts in torrential rain. Railway workers and trackside crews get the added benefit of RIS-3279-TOM Issue 2 compliance in the orange variant.

Key Features:

• Extreme Waterproof Protection: EN 343 Class 4:3 R rated with 11,000mm waterproofing and sealed seams. No water penetration, even in the harshest downpours.
  
• Outstanding Breathability: 50,000g/m²/24hrs moisture vapour transmission keeps you from overheating. The fabric draws sweat away so you're not clammy after a full shift.
  
• Railway Certified: Orange version meets RIS-3279-TOM Issue 2 standards for trackside work. Also EN ISO 20471 Class 2 certified for high-visibility tasks across all environments.
  
• Premium Stain Resistance: The finish repels oil, water, and grime effectively. Keeps the garment looking professional and maintains reflective properties in dirty industrial conditions.
  
• Reflective Tape & Piping: Maximum visibility in low-light conditions from all angles. Essential for roadside, construction, and railway work where being seen is critical.
  
• Practical Design: Zipped ankles fit easily over work boots. Side access openings for convenience. Double rule pocket and back pocket with flap for storage. Unlined construction for easy movement.
