HydroBlock Classic: Obermeyer independently third party tests all of its technical fabrics for performance verification. Obermeyer's high performance specialty fabrics use fully coated hydrophobic laminations and a superior DWR polymer coating for stain protection and coating integrity. HydroBlock Classic resists water penetration while allowing water vapor to pass creating a water-resistant breathable barrier.
Interior Windguard: Interior windguards ensure that the elements do not penetrate the closed zipper teeth and send a chill to your chest. Obermeyer has learned that when the weather is nasty and a fully zipped up front zipper is tucked under your chin, there's nothing better than the top of the windguard having fleece to minimize abrasion on your chin, especially in cold weather.
