Neo Glass is a brand new construction process which has been getting some rave reviews from the FCS team riders. By blending the finest nylon and long strand fibreglass they have created a fin with some exciting characteristics. Kai Otton, Felipe Toledo and Davey Cathels have been putting the Neo Glass fins through their paces and claim, they have plenty of drive and made my board feel alive. And are said to have a superb recoil, increasing drive and carrying speed through turns.
