With the Devaux UVBOY thread, enjoy a product whose technical qualities make all the difference at the water's edge. Its pearlescent hue delivers striking realism when crafting insect bodies and irresistibly attracts fish thanks to subtle plays of light. Its controlled elasticity ensures precise tying without twisting or sagging of the thread, even after successive wraps. The 35-meter spool guarantees many fly-tying sessions while maintaining ideal tension, essential for techniques such as tight winding on fine hooks.

Beyond its aesthetic advantages, the UVBOY thread stands out for its remarkable versatility. It meets the needs of amateur tiers as well as the requirements of professionals aiming to create exceptional patterns. Its natural sheen, designed to remain discreet underwater, maximizes fly effectiveness even in low-light conditions or under heavy fishing pressure. It is recognized as an attractiveness booster, both on wild trout runs and on waters with hard-to-impress salmonids.

To get the most out of the UVBOY thread, it is recommended to pair it with fine weighted heads and favor delicate patterns that highlight its shine. The thread's suppleness facilitates creating segments, rings and segmented bodies—essential to imitating aquatic insects. For nymph or chironomid tying, the ideal technique is to start with a classic base layer on the hook then wrap the UVBOY thread in even turns for a natural mirror effect. Use precise tools and natural or LED lighting to enhance the thread's brilliance throughout the tying process.

“An amateur tier for over 15 years, I adopted the UVBOY thread upon its release in 2024. Its strength is impressive for fine bodies and its shine attracts the wariest trout. This thread has clearly increased my hook-up rate, especially on heavily fished rivers. A true must for any modern tying enthusiast!”
