Poly Pro McFlylonFLY11
McFlylon is a bright, wavy polypropylene yarn that is great for many fly tying applications that require a light, floating material. It is also available in more colors than regular spooled polypro yarn and is especially suited for strike indicators, parachute posts, and underwings for stoneflies and terrestrials. McFlylon has just the right amount of sheen to give it just a little bit of sparkle and works great for both freshwater and saltwater fly patterns. We love this stuff!
