The polyyarn ties up smoothly and creates a natural-looking body on the hook. I’ve used it for several dry fly patterns and the results are consistent and attractive.

Lighter than water as described, and the color options are vibrant. It’s easy to work with and gives a clean taper when singed properly.

Great for beginners and experienced tyers alike. The yarn holds well and doesn’t fray easily. A little practice with singeing helps achieve the best profile.
