Key Benefits
- Waterproof rating of 15,000mm H2O to JIS L 1092 B for the main fabric, verified by test standard
- Vapour permeability of 15,000 g/m²/24h to JIS L 1099 B-1 maintains breathability during activity
- Linen bag with 10,000mm water resistance to JIS L 1092 B provides durable storage
- Double layer downbag construction enhances insulation retention
Problems It Solves
- Down jackets that lose insulation when exposed to moisture due to untested shell performance
- Lack of documented waterproof performance in the storage bag for transport and storage
- Insufficient breathability in insulated garments during moderate activity
Who It Is For
- Outdoor and lifestyle brands sourcing insulated jackets with test-verified waterproofing
- Importers needing a complete package with a protective storage bag
- Private-label buyers requiring a jacket with a natural-fibre bag component
Application Scenarios
- Winter urban wear in wet climates where a separate storage bag is needed
- Outdoor programmes requiring a lightweight insulated jacket with documented performance
- Travel use where the jacket is stored compressed and must retain loft
Technical Features and Construction
- Double layer downbag construction for improved insulation retention
- Tunnel hood with adjustable drawcord for weather sealing
- Full-length double zip front closure for ease of wear
- Elastic cuffs with thumb holes to seal the wrist
- Two front pockets with zip closures
- Inner pocket for secure storage
- Linen and royan blend bag with 10,000mm water resistance to JIS L 1092 B
Materials
- Main fabric shell: 100% poly with DWR finish tested to JIS L 1092

How It Is Made
- Padding is blended and filled in a double layer downbag construction
- Bag is assembled separately using 55% linen and 45% royan shell with 100% PU mid-layer
Quality Control and Testing
- Waterproof resistance of main fabric measured to JIS L 1092 B at 15,000mm
- Waterproof resistance of bag fabric measured to JIS L 1092 B at 10,000mm
- Vapour permeability measured to JIS L 1099 B-1 at 15,000 g/m²/24h
Certification
Customization Options
- Colourway beyond standard: available on request, specification TBC
- Label, hangtag and packaging: buyer supplied artwork
- Size grading and fit block: adjustable to buyer's specification
Compared With the Alternatives
| A standard storage bag without waterproofing | The linen bag has 10,000mm water resistance to JIS L 1092 B, protecting the jacket during transit |
|---|---|
| A single layer downbag | The double layer construction in YD-728-1 improves insulation retention and reduces heat loss |
Use and Care Guide
- Close the double zip fully before exposure to wet conditions
- Hang the jacket to regain loft after unpacking from compressed storage
- Reapply water repellent treatment after washing to maintain surface beading
- Store the jacket in the linen bag to protect the shell during transit
