Product Features
1. True Waterproof Protection for Outdoor Jackets
Our ePTFE membrane forms a dense microporous structure that blocks rain, snow, and high-pressure water while maintaining long-term waterproof durability-ideal for mountaineering, hiking, ski, and professional outdoor jackets.
2. High Breathability for Active Comfort
The micro-porous network allows vapor to escape efficiently, preventing overheating and moisture build-up during intensive outdoor activities. This ensures comfort in high-sweat and high-movement environments.
3. Lightweight & Flexible Lamination
The membrane's thin and flexible structure integrates smoothly with:
- Nylon and polyester woven fabrics
- Softshell textiles
- High-density performance fabrics
- Multi-layer outerwear materials
It supports 2-layer, 2.5-layer, 3-layer waterproof jacket constructions.
4. Superior Wind Protection
With complete windproof capability, our ePTFE membrane enhances thermal retention in jackets used in windy or cold climates.
5. Resistant to Harsh Outdoor Conditions
ePTFE is naturally resistant to:
- UV exposure
- Abrasion
- Temperature changes
- Chemical contaminants
This ensures performance jackets maintain long-term reliability and appearance.
