We use PrimaLoft insulation inside insulated garments for its warmth, compressibility, and soft comfort. While the human body uses energy to stay warm, PrimaLoft insulation uses a patented microfiber structure to help the body retain warmth and conserve energy.
The proprietary ultra-fine fibers of PrimaLoft insulation form a tight collection of air pockets that trap heat from your body and keep the cold out, providing an excellent warmth-to-weight ratio. When insulation gets wet, it loses these air pockets and consequently, its insulating properties. PrimaLoft ultra-fine fibers were developed to be water resistant so your insulation stays drier and maintains its insulating properties even when wet.
H2No® Performance Standard is Patagonia’s benchmark for waterproofness, breathability and durability, which ensures a high level of long-term performance backed by our Ironclad Guarantee.
H2No Performance Standard products undergo the most rigorous testing in the industry. In our “fab lab,” we use highly controlled tests to simulate actual-use. We test a fabric’s waterproofness by simulating light rain, prolonged rain and then forcing water through the fabric. We test breathability by measuring a fabric’s Moisture Vapor Transmission Rate (MVTR). And we test durability by subjecting fabrics to a “Killer Wash,” our proprietary wet flex test that simulates years of use and abuse.
The H2No Performance Standard for waterproof shell garments is 20,000 MM before, and 10,000 MM after our Killer Wash test (per JIS L 1092 B).
We promote fair labor practices, safe working conditions and environmental responsibility throughout the Patagonia supply chain.
