Orvis - Hy-Flote Shake-N-Flote Renew

No need to change flies or wait for a fly to dry off. Drop the fly into the desiccant still tied to the leader, close the lid, shake vigorously, and the fly is instantly dry. And you are back in business. 

The 2-part powder contains:

1. Water-loving crystals that suck water and fish slime off the fly, drying it thoroughly.
2. Water-hating powder that dusts fly fibers/hairs/hackles with a floatant that repels water so it stands up on its hackle points.
