The Obermeyer HydroBlock® Series is our engineered system of waterproof breathable coatings. Waterproof breathable fabrics consist of an outer layer called the “face fabric”, usually made of nylon or polyester, and a laminated polyurethane membrane or coating, that is finished with the latest Durable Water Repellant (DWR) coating.
Modern waterproof breathable fabrics are more sophisticated than ever and most are exceptionally waterproof at any price point with recent incremental gains in breathability, redefining adventure outerwear.
