Prisma is totally new fluorocarbon in Vision range. It has great knot strength and it is easy to tie, thanks to a special coating and slightly bigger stretch. It is still hard material so it gives you great turnover if you are using heavily weighted flies and because of fluorocarbon’s density it sinks, making it ideal for wet fly use. Prisma, like all other Vision tippet materials, come in colour coded, snap together & rotate spools. Best Seller!
