Built to Handle Extreme Cold – Certified Down to -40°C

When winter hits hard, Portwest's T400 PW3 Hi-Vis Winter Jacket doesn't mess about. This isn't your average hi-vis coat – it's engineered with Insulatex heat reflective technology that bounces your body heat back where it belongs, keeping you warm in conditions that would send most jackets packing. Combine that with proper waterproof construction and you've got cold-weather protection that actually works.

Key Features:

• Insulatex Heat Reflective Lining: Reflects body heat back to keep you warm in extreme conditions. Certified for protection down to -40°C under EN 342 standards with thermal resistance of 0.323 (M².K/W).
  
• Fully Waterproof Construction: 300D Oxford PU coated fabric with taped seams and PFAS-free Texpel™ Splash Eco finish. Water beads straight off the surface. The multi-layer construction includes a 190g polyester shell, 60g lining, and 170g filling for serious insulation.
  
• Maximum Visibility: Certified to EN ISO 20471 Class 3 (Class 2 for XS) and RIS 3279 TOM Issue 2 for railway work (Orange only). Heat-applied segmented reflective tape keeps you visible in low light. The fabric blocks 98% of UV rays with 40+ UPF rating.
  
• Five Practical Pockets: Zipped chest pocket, two side zipper pockets, inner chest pocket, and a concealed mobile phone pocket. Radio loops built in for communication devices. Everything stays secure and accessible.
  
• Concealed Detachable Hood: Ergonomically shaped hood tucks away when you don't need it. Contrast fleece collar protects against dirt whilst staying comfortable around your neck.
  
• Designed for Real Work: Twin-stitched seams throughout. Easy-grip pullers on all zippers work with gloves on. Drawcord adjustable hem, quick-dry knitted cuffs with hook-and-loop closures. The curved back hem provides better coverage when bending.
