Orvis Dry Powder Fly Float Hy-Flote Shake-N-Flote Renew keeps your flies floating higher longer and it is easy to use and temperature stable. Unlike many floatants it won't harden in the cold or melt in the heat. It also doesnt leave a film on the water. This product has a unique way of making your flies float because you can stick it in the bottle, shake it around, and once again, your fly will float on top of the water where the giant trout feed. Caution may be needed in the event that such large trout are attracted that you may get bit yourself. 2-part powder contains: Water-loving crystals that suck water and fish slime off the fly, drying it thoroughly Water-hating powder that dusts fly fibers/hairs/hackles with a floatant that repels water so it stands up on its hackle points.
