Key Benefits
- Moisture permeability of 10,000 g/m²/24h to JIS L 1099-B1
- DWR level 5 before washing, level 4 after washing to JIS L 1099-B1
- Two-layer construction with PU-membrane for consistent waterproof performance
- Terylene fabrics used in both jacket and undergarment for durability and moisture management
Problems It Solves
- Unverified waterproof claims without test standard documentation
- Breathability loss in high-moisture environments due to poor vapour transfer
- DWR degradation after washing leading to reduced water beading performance
Who It Is For
- Outdoor apparel brands sourcing technical outerwear with verified performance
- Private-label buyers requiring a functional base layer with documented fabric performance
Application Scenarios
- Outdoor work in wet conditions requiring sustained waterproof protection
- Active use in variable weather where breathability and water resistance are both needed
- Programmes requiring documented performance to JIS standards before production

Compared With the Alternatives
| A jacket without a membrane | GL04 has a PU-membrane for consistent waterproof performance |
|---|---|
| A single-layer fabric with no membrane | GL04 provides higher moisture permeability and better breathability |
| A jacket with a lower DWR level | GL04 maintains level 4 after washing, offering better long-term water resistance |
Use and Care Guide
- Apply DWR reproofing after washing to maintain level 5 water beading
- Avoid abrasion on the outer surface to preserve membrane integrity
- Dry flat or tumble dry low to preserve membrane and finish
