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. For fly tyers who want to liven up their flies, Sili Legs are also available in metallic versions. With so many options, it is easy to find a color of Sili Legs ideal for your needs.
