Orvis Hydros Fly Reel ( 2025 Model )The Hydros is now lighter and has a more protected drag mechanism. We took a great fly reel and made it better. The new Hydros fly fishing reel is the result of our desire to make something great that much better. We took a best selling reel and removed unnecessary material to further reduce the weight while stiffening the narrow spool, which minimizes line stacking. We changed the drag knob to be more ergonomically accessible and comfortable to use.
