The first layer is a soft feel and breathable non-woven fabric, the breathability means that it draws moisture away from the caravan. The second layer is a waterproof layer that protects the caravan from all moisture and helps ensure the fabric does not get waterlogged to increase lifespan and performance. The third layer is a reinforced non-woven fabric layer for additional protection that adds strength to the cover and gives the cover a better padding and thus gives your caravan better protection from road debris such as stones, grit and mud. The fourth layer (outer) is a non-woven fabric. It is the hardest wearing layer that is both waterproof and water repellent. This again helps protect the caravan from water and mud.
