ProtectPaper®
ProtectPaper®, developed by us in 2008 and trademarked in 2023, it is a groundbreaking fusion of paper, fabric and nano-technology.
This innovative material combines the natural texture of paper with the strength of cotton fabric, resulting in a unique feel that “wears like leather” and transforms over time like a beloved pair of jeans.
Coated with nanosilicon dioxide, ProtectPaper® is water-resistant and durable, ensuring that Wren’s designs protect their contents from the elements.
