Cork is naturally water-resistant, making it well suited for everyday accessories and home goods. This quality comes from cork’s closed-cell structure, which repels moisture.
How Cork Handles Moisture

Cork bark evolved to protect the cork oak tree from rain, heat, pests, and decay. Each cubic centimeter contains about 40 million air-filled cells, forming a closed-cell structure that resists water penetration. Cork repels water rather than absorbing it. This natural resistance helps protect items like wallets, bags, and coasters and placemats from rain, spills and condensation.
Everyday Use in Real Life

Cork’s natural water resistance makes it practical for daily situations, from protecting surfaces against condensation to handling light rain while on the go.
Cork vs. Other Materials

Compared to leather, cork performs especially well in damp environments. You can explore these differences further in our cork vs. leather comparison.
What Water-Resistant Means
Cork handles rain and everyday moisture easily, but it isn’t intended for prolonged submersion. While extended soaking isn’t recommended, cork dries naturally without cracking or warping. Its performance is best understood in the context of its natural properties, outlined in The Complete Guide to Cork.
