Every tyer needs a range of fluorescent threads, and Fluoro Brite is an exceptional choice. It’s a twisted fluorescent thread that untwists easily with a bobbin holder, allowing it to lay flat like floss. With vibrant UV properties, it creates patterns fish find irresistible.

Specially formulated for fluorescence, Fluoro Brite has a 240 denier (3/0) strength, perfect for hooks size 10 to 2/0. For smaller flies, it can be split to suit your needs. Use it as a tying thread, ribbing, body, hotspot, or even a tail.

For tails, fold Fluoro Brite into a loop, tie it in, cut to length, and tease fibers apart with a dubbing brush. This creates a crinkled, firelight effect, making your flies stand out.

Fluorescent materials have been attracting fish since the 1960s. Inspired by Joseph Keen’s Fluorescent Flies and Thomas Clegg’s The Truth About Fluorescents, Semperfli created Fluoro Brite for versatility and performance.

Fluorescent materials like Fluoro Brite work exceptionally well during low light, such as one hour before daylight and after nightfall. UV rays, invisible to us, light up flies underwater, making them highly visible to trout, salmon, and other fish.

Upgrade your tying kit with Fluoro Brite and create flies that stand out!
