3 in 1 Waterproof Jacket with Fleece for Children

A 3 in 1 waterproof jacket with fleece for children combines a removable insulated fleece liner with a waterproof and breathable outer shell, designed to provide adaptable thermal regulation and weather protection across varying seasonal conditions.

The outer shell is constructed from a laminated polyester fabric with a polyurethane coating, achieving a minimum hydrostatic head rating of 5,000 mm and a moisture vapor transmission rate (MVTR) of at least 3,000 g/m²/24h, ensuring resistance to light rain and snow while allowing sweat to escape during active use.

The detachable fleece liner is made from 100% polyester microfleece with a weight of 280 g/m², providing a thermal insulation value (CLO) of approximately 0.8 when worn alone, and can be zipped into the outer shell using a secure, YKK®-style coil zipper to form a combined system with enhanced cold-weather performance.

Design and Functional Integration

The jacket’s three configurations—outer shell only, fleece liner only, and combined system—allow users to adapt to temperature fluctuations without carrying multiple garments, reducing bulk and improving compliance with wear protocols in outdoor educational or recreational settings.

Adjustable cuffs with hook-and-loop closures and a drawcord-adjustable hem enable users to seal out wind and precipitation, while a storm flap over the front zipper minimizes water ingress at the closure point, maintaining the integrity of the waterproof barrier.

Reflective trim is integrated along the sleeves and back hem to increase visibility in low-light conditions, meeting the minimum reflectance requirements of EN ISO 20471 for non-professional use in environments with limited lighting.

Material Composition and Performance Characteristics

• Outer shell: 100% polyester with PU laminate; weight: 140 g/m²; tear strength (ASTM D2261): ≥8 N warp, ≥6 N weft
• Fleece liner: 100% polyester microfleece; weight: 280 g/m²; pilling resistance (ASTM D3512): Class 3 or better after 5 cycles
• Zipper: Coil type, nylon teeth, polyester tape; abrasion resistance: ≥10,000 cycles (ASTM D2097)
• Seam sealing: Critical seams taped with 15 mm polyurethane tape; waterproof integrity verified via spray test (AATCC 35)

The outer shell fabric is treated with a durable water repellent (DWR) finish, which causes water to bead and roll off the surface; this treatment is rated to withstand 20 wash cycles before reapplication is recommended to maintain surface performance.

Sizing and Fit Considerations for Pediatric Use

The jacket is available in size ranges corresponding to children’s height measurements: 90–100 cm (size 3–4 years), 110–120 cm (size 5–6 years), 130–140 cm (size 7–8 years), and 150–160 cm (size 9–10 years), with patterns developed using pediatric anthropometric data to accommodate growth layers and layering underneath.

Sleeve length and torso proportions are graded to allow freedom of movement during physical activity, with a minimum ease of 4 cm at the chest and 3 cm at the sleeve to prevent restriction when wearing additional layers such as base layers or school uniforms underneath.

The fleece liner is cut slightly smaller than the outer shell to ensure smooth zipping and to prevent bulkiness when worn alone, while the combined system maintains a streamlined silhouette to avoid snagging on backpacks or playground equipment.

Quality Control and Manufacturing Consistency

Each batch undergoes visual inspection for stitching integrity, zipper alignment, and seam tape adhesion, with a defect rate threshold of less than 2.5% for critical flaws such as misaligned zippers, open seams, or delamination of the waterproof coating.

Dimensional stability is assessed after five wash cycles at 40°C following ISO 6330, with acceptable shrinkage limited to ±3% in length and ±2% in width to ensure long-term fit retention across multiple seasons of use.

Colorfastness to washing, light, and perspiration is tested per ISO 105-B02, ISO 105-B04, and ISO 105-E04, with a minimum rating of 3–4 on the gray scale to prevent fading or staining when exposed to routine environmental conditions.

Applications in Educational and Recreational Environments

This jacket is commonly specified for use in forest schools, outdoor learning programs, and youth sports teams where children are exposed to variable weather for extended periods, enabling them to remain dry and thermally comfortable without overheating during high-activity phases.

The removable liner allows institutions to standardize on a single outer shell across seasons, reducing inventory complexity and replacement costs, while the fleece liner can be laundered independently for hygiene management in shared-use settings.

In regions with frequent light precipitation and fluctuating temperatures—such as coastal or upland temperate zones—the 3 in 1 configuration provides a practical solution that outperforms single-layer rainwear or heavy insulated jackets in terms of versatility and wear duration.

The combined system achieves a total thermal insulation of approximately 1.0 CLO, suitable for temperatures down to -5°C when worn with appropriate base layers, based on predicted thermal comfort models (ISO 11079) for children engaged in moderate activity.
