The first SUP specifically conceived for Water Sports Centers and Rental activity Solid is the Cressi Hydrosports SUP family designed specifically for professional rental. The use of Double Chamber Reinforced PLF technology and triple-layer anti-abrasion rail (the most resistant and robust composition in the whole collection) guarantee maximum structural rigidity and great safety during sessions at sea. The board is available in the All Round version with one seat and Tandem with two seats. Due to their intended professional use, the two versions of Solid have features designed to improve the experience of both the boards' end users and those who rent them. Numerous D-rings and handles are positioned along Solid's structure to facilitate hooking and transport. Furthermore, each side features special dedicated HIN (Hull Identification Number) spaces for customized numbering by the rental center.
