H2No Performance Standard
H2No is a testing standard rather than a single membrane. Patagonia specifies laminates from several suppliers and holds them to its own wet and wash cycle protocol.

Manufacturer specification
Published figures only — nothing estimated
- Owner
- Patagonia
- Membrane type
- Not publicly specified — H2No is a performance standard applied to laminates from more than one supplier
- Construction options
- Could not be verified from the accessible official documentation
- Waterproof rating
- Not publicly specified by manufacturer
- Breathability rating
- Not publicly specified by manufacturer
- Air permeability
- Not publicly specified by manufacturer
- Typical price segment
- Varies by garment.
- Weight characteristics
- Varies by face fabric and construction rather than by membrane alone.
- Durability characteristics
- Durability depends on the textile, laminate, seams, use and care; denier alone does not establish abrasion resistance.
- DWR requirements
- Face fabrics carry a durable water repellent finish. Repellency wears off with use and needs reproofing; the membrane itself is unaffected.
- PFAS / PFC information
- Check the current season's material declaration. Many brands have moved to PFAS-free repellent finishes, and platforms differ by year and by garment.
WaterproofJacket.com assessment
Our editorial analysis, not a manufacturer claim
Main advantages
- Recycled face fabrics across much of the range
- Consistent internal durability testing standard
- Strong repair and warranty support
Main disadvantages
- Because it covers several laminates, one H2No garment does not perform like another
- Numeric ratings are generally not published per garment
Best uses
- Hiking
- Travel
- Everyday rain
Poor uses
- Direct numeric comparison against rated fabrics
Care instructions
- Follow the garment label and official care instructions. Use the specified cleaner; Gore permits a small amount of suitable liquid detergent for conventional GORE-TEX outerwear. Avoid products those instructions prohibit.
- For DWR-finished garments, clean first and reproof only if needed, following garment and treatment instructions. Do not apply DWR to persistent-beading constructions such as SHAKEDRY.
- Tumble dry warm or press with a cool iron under a cloth if the care label allows, to reactivate the finish.
