Smoke Jumper
The Smoke Jumper is a trusted emerger pattern developed by Big Y Fly Co. and long favored by fly fishing guides, especially on the Bighorn River in Montana.
Designed to mimic mayflies and caddis flies, this fly is effective during all stages of a hatch—before, during, and after.
The CDC (Cotton Duckweed) material helps the fly sit naturally in the subsurface, making it ideal when fish are targeting insects that fall below the surface.

FAQ
What makes the Smoke Jumper effective during a hatch?
The CDC material allows the fly to sit naturally in the subsurface, which matches the behavior of insects that fall below the water surface. This makes it effective when fish are targeting subsurface insects during a hatch.
Is the Smoke Jumper suitable for use in still or moving water?
Yes, it performs well in both still and moving water, especially when fish are actively feeding on emergent insects.
Can the Smoke Jumper be used for trout fishing in cold water streams?

Austin Hart –
Used the Smoke Jumper on the Bighorn River and caught several trout during a caddis hatch. The CDC material kept it submerged and natural, and the fly mimicked the insects perfectly.
Joseph Young –
Great pattern for targeting fish during the transition phase of a hatch. It stayed in place well and worked well in moderate current.
John Randall –
Fished it before and after a mayfly hatch and saw consistent strikes. The design is subtle and realistic, making it a reliable choice for emergent insects.
