Comparable to Frog’s Fanny™, this lightweight white powder brings soaked dry flies back to life and makes nymphs more lifelike by creating a realistic gas bubble effect. The product comes with a lightweight brush attached to the lid that allows you to accurately and delicately apply the powder to the wings of a drowned fly. Our fly dust will not leave a slick on still waters or spring creeks. A great product for delicate dries and those with CDC. 1 oz. bottle.
