What is H2No?
The Patagonia H2No is the performance benchmark by Patagonia for waterproofness,breathability,and durability which ensures a high level of long-term performance backed by Patagonia's Ironclad Guarantee. H2NO Performance standard products undergo rigorous testing - their Killerwash is Patagonia's Proprietary wet flex test that simulates years of use in drenching conditions. The H2NO waterproof performance standard for shell garments is 20,000 mm before and 10,0000 after the Killerwash test (per JIS L 1092 B). Patagonia also send their ambassadors and testers into the field to punish these garments in every possible condition to expose any potential weaknesses in materials or construction. Patagonia reject any garments that does not pass their tests, regardless of technology or fabric supplier. Whether it's a bomber 3-layer alpine shell or a pared-down rainwear piece, the same rules apply.
2-layer H2No® Performance Standard shell fabrics are completely waterproof, windproof and breathable. They combine a water-repellent shell fabric with a waterproof/breathable membrane. They also have an internal Taffeta or mesh lining for increased durability and next-to-skin comfort.
2.5-layer H2No® Performance Standard shell fabrics are waterproof, windproof, breathable and highly packable. They combine a water-repellent shell fabric with a waterproof/breathable membrane and protective top coat barrier designed to allow the garment to be constructed without the need for an internal lining fabric. A distinctive raised print layer is applied for decreased surface tension and increased moisture management.
3-layer H2No® Performance Standard fabrics are waterproof, windproof and breathable by virtue of an advanced combination of elements: a water-repellent shell fabric, a waterproof/breathable membrane, and an ultralight knit backer. The entire fabric package is highly packable, comfortable next-to-skin, and built to withstand long term exposure in extreme environments.
