Can Custom Down Jackets Be Waterproof or Windproof?
OEM & ODM solutions for weather-protective down outerwear
Yes — custom down jackets can be made waterproof, water-resistant, and/or windproof through appropriate shell fabrics, coatings or membranes, seam construction, and functional design details. This is a standard OEM and ODM capability at Ginwen.
Waterproof vs. Water-Resistant vs. Windproof
Understanding functional performance differences- Waterproof: Blocks water penetration under pressure, typically measured by hydrostatic head (mm).
- Water-resistant: Repels light rain or snow, usually via DWR treatment, but not prolonged pressure.
- Windproof: Prevents airflow penetration to reduce convective heat loss.
Many down jackets combine windproof and water-resistant performance for urban use, while technical outerwear may require fully waterproof and windproof construction.
How Waterproof & Windproof Performance Is Achieved
Materials, treatments, and construction working together- Shell fabrics: Waterproof laminates (2L / 2.5L / 3L), coated nylons or polyesters, tightly woven windproof shells
- Surface treatments: Durable Water Repellent (DWR), PU or TPU coatings
- Seam construction: Critical or full seam sealing, reinforced stress points
- Design details: Storm flaps, laminated plackets, protected pocket entries
- Insulation protection: Down-proof linings, water-resistant down, or synthetic eco-fill
Typical Performance Levels (Guideline)
Matched to real-world use cases| Requirement | Typical Construction |
|---|---|
| Light rain & wind | Windproof shell with DWR treatment |
| City winter rain | Water-resistant shell with storm flaps |
| Snow & prolonged rain | Waterproof laminate with seam sealing |
| Active outdoor use | Waterproof & windproof shell with breathable lining |
Waterproof ratings (for example, 5,000–20,000 mm) and breathability targets are defined by the buyer and confirmed before sampling.
