As their name suggests, Sili Legs are silicone impregnated legs. Made of silicone, they have a translucency and flexibility that is unmatched by conventional rubber legs. This allows fly tyers to choose leg colors that blend in with the overall color scheme of their flies thus creating realistic looking fly patterns.

The barred and speckled varieties of Sili Legs are ideal for creating realistic fish catching fly patterns. The nymph size is especially good for making legs on size 12 or smaller flies.
