Prism is a brand new Fleocarbon in Vision's range. It has high knot strength and is easy to tie thanks to a special coating and a little higher stretability than usual. However, it is still a hard material that gives you fantastic rolling if you use heavy flies and thanks to the density of the fluorocarbon, it easily breaks the surface, which is ideal for wet flies, streamers, etc. Prisma, as all other vision paw material comes on a color coded, interconnection and rotating coil.
