Technical Overview

This raincoat combines a waterproof outer shell with a bonded fleece lining to provide thermal insulation and moisture protection in wet, cool environments. The three-layer construction features a hydrophilic polyurethane membrane laminated between a durable nylon face fabric and a 200gsm polyester fleece backing.

The membrane achieves a hydrostatic head rating of 8,000mm, resisting water penetration under sustained pressure while maintaining a moisture vapor transmission rate (MVTR) of 5,000 g/m²/24h to manage internal condensation during moderate activity.

Seams are sealed using 15mm wide thermoplastic polyurethane tape applied via hot-air welding, eliminating needle holes that could compromise waterproof integrity. This method exceeds the requirements of EN 343 Class 3 for protective clothing against rain.

Design and Functional Features

The attached hood features a three-point adjustment system: rear drawcord for volume control, side toggles for lateral fit, and a stiffened brim made from molded EVA to maintain shape in wind. Vertical orientation of the hood opening accommodates hard hats or helmets when required.

Front closure utilizes a coiled polyester zipper with storm flap secured by concealed magnetic snaps, reducing wind-driven rain ingress at the primary closure point. Zipper teeth are coated with PTFE for smooth operation after repeated wet/dry cycles.

Two lower handwarmer pockets are positioned above the hip belt line to remain accessible when wearing a harness or backpack. Pocket bags are made from brushed tricot to minimize abrasion against skin, with drainage holes at the lower corners to prevent water accumulation.

Adjustable cuffs incorporate a two-layer system: inner Lycra® gaiter with thumb loop and outer hook-and-loop tab, allowing users to seal the sleeve opening over gloves or adjust for ventilation. Hem drawcord uses barrel locks to prevent slippage when tightened.

Material Specifications

All materials comply with OEKO-TEX® Standard 100, Class 2 for skin-contact textiles. The TPU membrane is polyester-based and does not contain phthalates or bisphenol A.

Performance Characteristics

Thermal retention testing shows the fleece lining maintains 85% of its insulating value when damp, outperforming standard polyester fleece which typically retains 60-70% under similar conditions. This is attributed to the low moisture absorption (<0.5%) of the specific polyester fiber used.

Rain resistance is validated through ISO 811 testing, where the fabric withstands 8,000mm water column for 5 minutes without leakage. Spray rating (ISO 105-E04) achieves Class 4 (90% surface dryness) after 20 minutes of continuous spraying at 10 L/min.

Breathability is measured via ISO 11092 (sweating guarded hotplate), yielding a total thermal resistance (Ret) of 6.5 m²·Pa/W, classifying the garment as breathable for light to moderate work according to ISO 11092 guidelines.

Dimensional stability after 5 wash cycles at 40°C shows <2% shrinkage in length and <1.5% in width, meeting ISO 6330 requirements for residential laundering. Colorfastness to washing exceeds Grade 4 on the grey scale.

Applications and Use Cases

This garment is suited for outdoor operations in temperatures between -5°C and 10°C where precipitation is expected, such as utility line inspection, municipal maintenance, or agricultural monitoring. The fleece lining eliminates the need for a separate mid-layer in these conditions, reducing bulk and donning time.

The adjustable hood and sealed seams make it appropriate for environments with wind-driven rain, including coastal infrastructure work or open-yard logistics. Pocket placement and cuff design accommodate tool belts and gloves commonly used in field service roles.

While not designed for prolonged immersion or high-intensity aerobic activity, the MVTR allows comfortable wear during intermittent tasks like meter reading or site surveys where metabolic rates fluctuate between 1.5 and 3.0 met.

Quality Assurance and Testing

Each production lot undergoes hydrostatic head testing on three random samples per 1,000 units, with acceptance criteria of ≥7,500mm. Seam seal integrity is verified using a dye penetration test per AATCC Test Method 127, requiring zero leakage through taped seams.

Fleece lining weight is checked via random sampling, with tolerance of ±10gsm from the 200gsm target. Color consistency is monitored using a spectrophotometer with ΔE < 1.5 against the approved master shade under D65 illumination.

Finished garments receive a functional inspection including zipper operation over 10 cycles, drawcord tension measurement, and hood adjustment verification. AQL 2.5 is applied for major defects (e.g., open seams, missing components) and AQL 4.0 for minor defects (e.g., stitch irregularities).

Customization Options

Standard sizes range from XS to 3XL in women's specific grading, with torso length proportional to chest measurement. Sleeve length and torso dimensions can be adjusted in 25mm increments upon request, subject to pattern regrading fees.

Color options include navy, black, olive, and charcoal as stock items. Custom Pantone matching is available for orders exceeding 200 units, with laboratory dip approval required before bulk production.

Reflective trim compliant with ANSI/ISEA 107-2020 can be added to sleeves, shoulders, or back in 50mm or 100mm widths. Alternative pocket configurations (e.g., chest pockets, internal security pocket) are feasible with pattern modification.

For specialized environments, the TPU membrane can be substituted with a version offering increased breathability (MVTR up to 12,000 g/m²/24h) or enhanced chemical resistance, though this may affect hydrostatic head rating.

Packaging and Logistics

Garments are folded using a standardized method to minimize creasing, then placed in individual polybags made from 50μm LDPE with UV inhibitor. Each bag includes a silica gel packet (5g) to control moisture during transit.

Standard packing configuration is 20 units per carton (60cm x 40cm x 30cm), gross weight approximately 12kg. Cartons are marked with barcodes containing SKU, size, color, and lot number for warehouse scanning.

For export shipments, cartons are stacked on heat-treated pallets and secured with PET strapping. Corner boards and top/bottom protectors are used to prevent damage during handling. Shipping marks comply with ISPM 15 and include handling symbols per ISO 780.

Care and Maintenance Instructions

Machine wash cold (30°C) on gentle cycle with mild detergent. Avoid fabric softeners and bleach, as these can degrade the TPU membrane’s hydrophobic properties. Tumble dry low or line dry away from direct heat.

To restore water repellency after extended use, apply a fluorocarbon-free DWR treatment spray specifically designed for breathable membranes. Reapplication is recommended after 10-15 wash cycles or when water no longer beads on the surface.

Do not dry clean, as solvents can delaminate the membrane from the face fabric. Store in a cool, dry place away from direct sunlight to prevent UV degradation of nylon and elastic components.
