This product page details the technical specifications, material composition, and functional design of women's petite rain jackets manufactured in China for industrial and commercial procurement. The information is intended to support informed purchasing decisions by engineers, procurement specialists, and OEM buyers seeking reliable rain protection solutions tailored to smaller frame dimensions.

All specifications described are based on standard production capabilities and are subject to confirmation during quotation. Customization options are available upon request to meet specific end-use requirements.

The jacket is engineered with adjusted proportional scaling to accommodate women with petite statures, typically defined as heights under 160cm and corresponding torso and limb measurements. Key dimensional adjustments include shortened sleeve length, reduced torso height, and narrowed shoulder width compared to standard women's sizes, while maintaining functional ease of movement.

Pattern grading follows ISO 8559-1 principles for size allocation, ensuring consistent fit across the petite size range (typically XXS to XS in international sizing). Armhole depth and sleeve taper are recalibrated to prevent restriction during arm elevation, a critical factor for users performing overhead tasks in wet conditions.

The garment maintains a balanced silhouette to avoid excess fabric accumulation at the waist or hips, which could compromise water runoff or create snag hazards in industrial environments.

The primary outer shell is constructed from 100% polyester filament yarn with a minimum denier of 150D, providing a balance between tear resistance (ASTM D2261) and flexibility. The fabric undergoes a polyurethane (PU) coating process applied to the reverse side, achieving a hydrostatic head rating of ≥3,000 mm H₂O under JIS L 1092 Method B, sufficient for moderate to heavy rainfall exposure.

Seam sealing is implemented using heat-activated polyurethane tape on all stitched joints, preventing capillary leakage. The tape width is minimum 20mm and applied with consistent pressure and temperature control to ensure adhesion strength exceeding 1.5 N/mm (ASTM D413).

A durable water repellent (DWR) finish is applied to the outer surface using a C6-based fluoropolymer formulation, rated for ≥20 wash cycles before reapplication is recommended (AATCC Test Method 22). This finish reduces surface wettability without compromising breathability.

To mitigate internal condensation buildup during physical activity, the jacket incorporates a microporous polyurethane laminate with a moisture vapor transmission rate (MVTR) of ≥5,000 g/m²/24h (ASTM E96 BWB). This allows sweat vapor to escape while maintaining liquid water resistance.

Underarm ventilation eyelets are laser-drilled with a diameter of 3mm and spaced at 25mm intervals, covered by hydrophobic mesh to prevent water ingress. These are positioned to align with natural axillary movement patterns, enhancing airflow without sacrificing seam integrity.

The inner lining is a 100% polyester tricot mesh with a weight of 40gsm, designed to wick moisture away from the skin and reduce cling. The mesh structure provides minimal thermal retention, making the jacket suitable for use in temperatures ranging from 5°C to 20°C.

The front closure utilizes a coil-type nylon zipper with a width of 5mm, featuring a storm flap that overlaps by ≥20mm on both sides. The zipper tape is polyester-based with a tensile strength of ≥180 N (ASTM D2061) and is protected by a water-resistant coating.

Adjustable hook-and-loop cuff straps are positioned at the distal end of each sleeve, allowing circumference reduction of up to 40mm to seal against water ingress. The straps are laminated with a TPU film to prevent delamination after repeated flexing.

The hem includes an internal drawcord with a diameter of 3mm, threaded through polyester eyelets and secured with a barrel lock. This enables circumferential adjustment of the bottom hem by ±50mm to improve fit and prevent water entry during movement or wind exposure.

Two external welt pockets are positioned at the hip level, each with an opening dimensions of 140mm (width) × 80mm (height). The pocket bags are made from the same coated polyester as the shell and are accessed via a vertical zipper with a storm flap extending 10mm above and below the zipper track.

An internal security pocket is located on the left chest, measuring 120mm × 90mm, constructed from uncoated polyester mesh for visibility and quick access. It is designed to hold small essentials such as access cards or tools without adding bulk.

Reflective elements are optionally available as 20mm wide heat-transfer strips compliant with EN ISO 20471 Class 2, positioned on the sleeves and back for low-light visibility. These are applied using a pressure-sensitive adhesive backing tested for 50 wash cycles.

Each jacket is folded using a standardized flat-fold method to minimize creasing and packed into a low-density polyethylene (LDPE) bag with a thickness of 0.05mm. The bag is sealed via heat sealing and includes a desiccant packet (silica gel, 5g) to control moisture during transit.

Carton packaging consists of single-wall corrugated fiberboard with a burst strength of ≥275 kPa (ISO 2758), dimensions optimized for the folded garment size (typically 35cm × 25cm × 5cm per unit). Master cartons hold 20–25 units depending on size variation.

Labels include a woven care label (polyester/cotton blend) sewn into the side seam, detailing material composition, care instructions (machine wash 30°C, tumble dry low, do not bleach), and size identification. A removable hangtag provides barcode and SKU information for inventory systems.

The jacket is commonly specified for use in outdoor service industries where personnel require reliable rain protection without overheating, such as facility maintenance, event staffing, and light logistics operations in temperate climates. Its compact packability makes it suitable for storage in vehicle glove compartments or tool kits.

In educational or institutional environments, it is often selected for field trip supervision, campus security patrols, or outdoor instruction roles where a professional appearance and freedom of movement are priorities. The petite cut ensures proper fit for a significant portion of the female workforce in these sectors.

While not designed for prolonged exposure to extreme weather or chemical splashes, the jacket provides effective barrier protection against wind-driven rain and light snow, making it a practical layer for seasonal use in regions with intermittent precipitation.
