Troutline UVR San Juan Wiggle Worm Bodies are made from a soft and highly flexible TPR material designed to create maximum movement underwater. Developed especially for modern San Juan Worm patterns, this material combines the lively action of squirmy-style bodies with a textured surface that generates extra vibration and water displacement even in the slowest currents.
Unlike smooth worm materials, the textured structure creates a more dynamic and natural movement, making the fly appear alive and extremely attractive to trout, grayling and other opportunistic fish species.
The UVR effect adds subtle visibility underwater without making the pattern too aggressive, helping fish detect the fly faster in colored water, deep pools or low-light conditions.
