Fly Box UV Straggle features a neat 5mm additional UV fibre which has been woven throughout the strong & reliable core. A brilliant material to incorporate into most small-water & reservoir patterns, this has proven it's worth time & time again as thorax's on nymphs, fine bodies on wet flies & even on gold head lures. This material is professionally dyed using state of the art pressure dying machines, fully computer controlled to ensure 100% colour consistency & intensity through the full range of Fly Box fritz fly tying materials!
