High N Dry powdered desiccant and floatant was designed with special and unique materials, and compliments their Gel and Liquid floatants. Eventually your files will become water logged, or slimed by a great fish. This product is terrific for those fly-fishers that prefer a shake and dry floatant, but can also be used to revive that drowned fly and then refloated with High N Dry’s Gel or Liquid Floatants. Field and lab tests show it to be the best performing floatant available and it is not flammable and it contains no organic solvents, 100% solids and is environmentally friendly.
