Wapsi UTC Ultra GSP Fly Tying Thread

Wapsi UTC Ultra GSP Thread is an exceptionally strong fly tying thread made from gel-spun polyethylene, offering outstanding tensile strength with minimal bulk. Its supple fibers can lay flat for smooth, even wraps while providing the holding power needed to secure bulky materials without breaking. Lighter deniers are ideal for small trout flies and delicate patterns, while heavier deniers excel at spinning deer hair, securing streamer materials, and tying larger freshwater and saltwater flies. Available in multiple denier sizes, Ultra GSP provides reliable strength and versatility for everything from small nymphs to large bass bugs. Each spool contains 50 yards of thread.
