The Gore-tex alternative that costs 38% as much — and lasts longer in sun and cold.
GPOWER's nano-porous functional membrane delivers 10,000 g/m²/24h breathability, 15,000 mmH₂O waterproof rating, and outperforms the market leader on UV resistance (500h vs 300h) and low-temperature flexibility (-40°C vs -25°C). At ¥20-22/m² versus Gore-tex's ¥58.
Three material families. Three deal-breaking flaws.
Outdoor apparel and protective equipment manufacturers have been forced to choose between expensive imports, fragile alternatives, or environmentally problematic options. GPOWER ends that compromise.
ePTFE (Gore-tex class)
Pros: Gold-standard breathability + waterproof.
Cons: Extremely costly (¥58+/m²), import-dependent supply chain, UV degrades after 300h, brittle below -25°C.
Polyurethane (PU) film
Pros: Low cost, good waterproofing.
Cons: Poor breathability leads to sweat buildup, hydrolytic degradation, poor long-term durability.
Porous PE / PP films
Pros: Lightweight, inexpensive.
Cons: Low mechanical strength, easy tearing, dust clogs pores rapidly, poor reflectance control.
Nano-porous engineering that beats ePTFE where it counts
GPOWER's breathable membrane uses a tunable nano-porous structure with high surface area and precisely controlled pore size distribution. The result: water droplets can't penetrate (15,000 mmH₂O), but water vapor passes freely (10,000 g/m²/24h) — and so does sound.
- Matched breathability — 10,000 g/m²/24h MVTR, same class as Gore-tex Pro (ASTM E96).
- 67% better UV life — 500h with zero degradation vs Gore-tex's 300h limit (ASTM G154).
- -40°C cold flexibility — stays pliable where Gore-tex turns brittle (ASTM D2137).
- Sound-permeable — unique among waterproof membranes. Ideal for speaker/electronics covers.
- 38% of Gore-tex price — ¥20-22/m² domestic production, no import lead times.

Where this membrane changes the product economics
Outdoor apparel
Hard-shell jackets, soft-shell mid-layers, rain gear, ski wear. Gore-tex-level performance at 38% of the BOM cost. Better UV means longer garment life in sunny climates.
Electronics protection
Speaker grilles, microphone covers, smart device enclosures, outdoor sensor housings. Unique sound-permeability + waterproof combination that ePTFE cannot offer.
Tents & shelters
Camping tents, event canopies, emergency shelters. Lightweight, packable, withstands prolonged sun exposure without degradation.
Footwear
Hiking boots, work shoes, safety footwear uppers. Keeps feet dry while letting moisture escape. -40°C flexibility means winter boots stay pliable.
Medical & hygiene
Surgical gowns, protective coverings, sterile packaging barriers. Breathable comfort meets fluid-proof protection.
Industrial filtration
Ventilation membranes, filter media, dust-proof breathable covers for machinery enclosures.
