The Flesh Fly 4 looks and floats exactly like a real insect. I’ve used it in several streams and caught two trout on it during a morning drift. It’s well-made and holds up well in the water.

Great detail in the feathering and natural movement. It’s a bit heavier than expected, but that adds to its realism. Works well in clear water conditions.

This fly has become my go-to for spring fishing. The way it drifts and the fish respond to it is impressive. I’ve used it in both morning and afternoon casts.
