We are very excited to have the Neil Pryde Experience packages. These are phenomenal windsurfing sail packages. The 5.5m and 6.5m are both designed for the fun, easy, and exciting style of windsurfing that comes with windsurfing on a Stand Up Paddleboard. They are not limited to SUP's, but that it is certainly where they deliver the most fun. Many sails geared towards SUP sailing use heavy materials and older shapes. The Experience on the other hand has the best materials and high-performance shape to give an exciting feel to all levels of riders.
