Wapsi UTC Ultra Thread 140 The Wapsi UTC Ultra Thread 140 is a go-to choice for fly tyers who want strength, versatility, and a clean, professional finish. Constructed from slightly bonded continuous polyester filaments, this thread lays flat on the hook, allowing for smooth wraps and minimal bulk. With its vibrant sheen and excellent colour retention, your flies will maintain their visual appeal over time. Despite its fine diameter, UTC 140 is exceptionally strong, making it suitable for a wide variety of fly patterns and tying techniques.
