Mens 4Xl 5Xl Waterproof Jacket Rain Suit
Men's 4XL 5XL Waterproof Jacket Rain Suit
Engineered for industrial environments where prolonged exposure to precipitation is expected, this rain suit combines seam-sealed waterproofing with articulated mobility to maintain worker comfort and protection during extended outdoor operations.
Material Composition and Waterproof Performance
The outer shell utilizes a 300D polyester oxford weave with a polyurethane (PU) coating rated at 5,000mm hydrostatic head, verified under ISO 811 test conditions. This specification ensures resistance to wind-driven rain and light spray without internal condensation buildup during moderate activity.
Seams are sealed using 15mm wide thermoplastic polyurethane tape applied via heat-bonding process, eliminating needle-hole leakage points. The coating maintains flexibility down to -10°C, preventing brittleness in cold-weather storage or use.
Design Features for Extended Wear
The jacket incorporates a storm flap with hook-and-loop closure over the primary zipper, reducing water ingress at the front opening. Adjustable hook-and-loop cuffs and a drawcord hem allow users to seal gaps against wind-driven moisture.
Ventilation is provided through two 10cm underarm eyelets with corrosion-resistant brass grommets, enabling passive airflow without compromising waterproof integrity. The hood features a laminated brim and elastic face opening to retain positioning during head movement.
Bib-style overalls include reinforced double-layer knees with abrasion-resistant nylon patches, extending service life in crawling or kneeling positions. Adjustable suspenders with quick-release buckles accommodate layering over insulated coveralls.
Sizing and Fit Specifications
Available in 4XL and 5XL dimensions, the suit follows ANSI/ASME B89.1.13M sizing standards for industrial outerwear. Chest measurements range from 132cm to 140cm (4XL) and 140cm to 148cm (5XL), with corresponding sleeve lengths of 92cm and 95cm.
The torso cut provides 8cm of ease over base layers, allowing unrestricted movement during tool handling or ladder climbing. Inseam length is 82cm for both sizes, with a 4cm taper at the ankle to prevent snagging on equipment.
Typical Industrial Applications
This rain suit is specified for utility workers performing line maintenance in wet conditions, where electrical insulation of underlayers must remain dry. Municipal crews use it during sewer inspection and storm drain cleaning, where splash resistance and abrasion durability are critical.
In food processing facilities, the smooth PU surface facilitates washdown compliance with FDA 21 CFR §177.1520 for indirect food contact surfaces. Agricultural workers apply it during pesticide spraying operations, relying on the chemical-resistant coating to prevent permeation of water-based solutions.
Quality Control and Testing
Each batch undergoes spray testing per AATCC 35, where specimens are subjected to 100L/hour water spray for 5 minutes with no more than 1g weight gain accepted. Colorfastness to light is evaluated using ISO 105-B02, requiring a minimum rating of 4 after 20 hours xenon arc exposure.
Dimensional stability is verified after 5 wash cycles at 40°C, with shrinkage limited to 2% in warp and weft directions. All hardware components are cycle-tested to 5,000 operations for zipper retention and 1,000 for hook-and-loop strength.
| Parameter | Test Method | Acceptance Criteria |
|---|---|---|
| Hydrostatic Head | ISO 811 | ≥5,000mm |
| Seam Strength | ASTM D751 | ≥200N/50mm |
| Tear Resistance | ASTM D2261 | ≥25N |
| Colorfastness to Wash | ISO 105-C06 | ≥3-4 |
Customization Options
Alternative coatings include PVC-free thermoplastic polyurethane (TPU) for applications requiring phthalate-free compliance, or a fluoropolymer finish for enhanced resistance to oil-based contaminants. Reflective tape widths of 5cm or 7cm can be positioned per ANSI/ISEA 107-2020 Class 2 or 3 specifications.
Logo application is available via screen printing or heat transfer on the left chest and back yoke, using inks rated for 50+ wash cycles. Extended sizes beyond 5XL are offered upon request, with pattern grading adjusted to maintain proportional sleeve and torso dimensions.
Packaging and Lead Time
Units are packed in polyethylene bags with desiccant packs, then placed in recycled cardboard cartons labeled with size, batch number, and care instructions. Standard lead time is 15–20 working days for stocked materials; custom colors or coatings extend to 25–30 days.
To request a quotation, provide required sizes, coating preference, and any branding specifications. Samples are available for evaluation upon receipt of technical specifications and intended use details.
