No, 100% PU (polyurethane) is generally not waterproof on its own. While PU has water-resistant properties, fabrics coated with 100% PU often require additional treatments or coatings to be entirely waterproof. For applications demanding full waterproofing, look for terms like 'waterproof PU coatings' that indicate added layers or treatments have been applied to enhance waterproof performance.
