Marine Grade Sunlitec Fabric (MGSF) We want to introduce our newly developed thermal welded 3 layers Sunlitec fabric. The outer layer of Sunlitec is the special high-performance synthetic fabric similar to Acrylic fabric. It is resistant to sun light UV and many harsh chemicals including salt water. The mid layer is the water resident micro poly fabric foam. It is resistant to temperatures from outside and inside as well as impeding the water from going through and providing breathable performance. The inner layer is the marine grade polyester 300D for protecting the tear and wear from inside and as back support. After the Sunlitec manufacturing process, all three layers stay together as one fabric. It has a solid structure, better performance, looks great and is light weight. We are the only company to produce these boating accessories with Marine Grade Sunlitec Fabric (MGSF). We hope you will enjoy these high quality and affordable accessories.
