Sage Thermo Fly Reel
The Sage THERMO Fly Reel is built for the biggest, hardest-pulling fish we can target with a fly rod. Giant trevally, tarpon, tuna, billfish, sharks, and other serious bluewater species demand a reel with enormous backing capacity, a rigid frame, and a drag that can maintain heavy pressure through long, blistering runs. That’s exactly what the THERMO was designed to do.
At its core is Sage’s Ultra-Robust Sealed Carbon System (SCS) drag, capable of producing up to 20 pounds of drag while maintaining smooth, consistent pressure throughout the fight. Extra-large carbon brake discs efficiently dissipate heat, helping prevent drag fade as a fish strips hundreds of yards of backing.
The THERMO is fully machined from 6061-T6 aerospace-grade aluminum for strength and durability.

FAQ
What makes the Sage THERMO reel suitable for large, powerful fish?
The THERMO features Sage’s Ultra-Robust Sealed Carbon System (SCS) drag, capable of maintaining up to 20 pounds of consistent pressure during long fights with large fish like tarpon, tuna, and billfish.
How does the drag system prevent heat-related performance loss?
The extra-large carbon brake discs efficiently dissipate heat generated during prolonged fishing runs, helping to prevent drag fade when a fish pulls hundreds of yards of backing.
Is the reel suitable for use with fly rods?
Yes, the Sage THERMO is specifically designed for fly rod use and is built to handle the demands of large, powerful bluewater species.

Fought a massive tarpon and the drag held strong throughout the entire run. The heat dissipation was noticeable and the reel didn’t lose pressure even after 300 yards of line. Solid build and reliable performance in rough conditions.

Used it on a deep-sea trip with tuna and billfish. The drag system stayed consistent and the carbon brake discs kept the heat down. No drag fade even during long pulls. Highly recommended for serious anglers.
Anna Tucker –
Great for big fish. The reel feels sturdy and the drag is smooth. A bit heavy, but worth it for the performance. Would use it again in similar conditions.
