Portwest S433 Jacket: Engineered for Waterproofing and Extended Thermal Coverage

The S433 jacket from the Iona Traffic series is a comprehensive weather protection solution, designed for professionals who require superior shielding against rain and wind without sacrificing functionality. Thanks to its parka-style cut, it offers extended coverage below the waist, ensuring the wearer remains dry in extremely wet conditions. Made from durable 300D Oxford fabric, this garment combines high mechanical durability with a nighttime visibility system using reflective tapes, ideal for industrial, logistics, and transportation environments.

Why is this equipment vital for operations?

• Industrial-Grade Waterproofing: The fabric features a PU coating and heat-sealed seams that ensure total resistance to water penetration, keeping the operator dry and productive even during persistent storms.
• Thermal Homeostasis Management: Equipped with a 160g quilted lining, this jacket efficiently retains body heat, acting as an insulating barrier against cold and reducing the risk of fatigue from thermal exposure.
• Technical Storage Capacity: Unlike short jackets, the S433 incorporates large-capacity pockets with protective flaps, allowing for the secure storage of hand tools, shipping documents, and mobile devices against moisture.

Regulatory Compliance Analysis

This equipment complies with the EN 343 standard (Waterproofness and Breathability Class 3:1), guaranteeing certified protection against rain. Its reflective tapes are configured to maximize personnel detection in low-light conditions, offering a superior passive safety solution for areas where high fluorescent visibility is not required but nighttime detection is essential.

• Outer Fabric: 100% 300D Oxford Polyester with stain-resistant finish (190g).
• Insulation: 160g quilted lining for constant heat retention.
• Detailed Functionality: Adjustable concealed hood, elasticated windproof cuffs, and access for customization (embroidery or printing).
• Sun Protection: UPF 40+ factor that blocks 98% of ultraviolet radiation.
