We selected the best materials to make the most performing, lightest, strong and fast boat of the world. We don't use the standard cheap PVC used for common inflatable boats, we use the MEHLER TEXNOLOGIES VALMEX® FABRIC 0.9mm 1100 dtex, made in German. ​ Several layers of PVC are combined with a Polyester base fabric of high strenght, These layers give flexibility, elasticity, airtightness and resistance against mechanical damage. This means Your NEPTVN PRO 400 is resistant to abrasion , UV rays and weather, is dirt-repellent and insensitive to high temperature conditions. ​ Every PVC parts of the NEPTVN PRO 400 are not simply glued, are HOT WELDED with a process that makes them structurally eternal.
