Todd Wapsi Ultra Thread UTC 70 Wapsi Ultra Thread UTC 70 is a high-quality fly-tying thread engineered from the ground up to meet the demands of serious fly tyers. Unlike many generic threads, Ultra Thread was specifically designed for fly tying, with carefully selected materials and construction to deliver superior performance, durability, and control. The UTC 70 size is perfect for tying smaller flies while still offering excellent strength and control. It is especially well-suited for dry flies, nymphs, and midges in size 14 or smaller, and is also useful for maintaining low bulk on larger flies where precision is important. Made from premium nylon, the thread stretches slightly to improve grip on materials and provide consistent tension while tying. Its flat profile allows it to wrap smoothly on the hook shank, minimising thread build-up and making it ideal when tying close to the hook eye or creating small, clean fly patterns. Light waxing gives the thread a smooth feel while reducing bulk, and allows head cement to fully penetrate the thread for improved fly durability. The non-bonded multifilament construction also makes it ideal for split-thread techniques. Key Features Perfect for Small Flies – Ideal for tying dry flies, nymphs, and midges size 14 or smaller.
