Overview

The Umpqua Flexy Stone in Black is a durable, fast-sinking stonefly imitation designed to tackle deep currents, pocket water, and fast runs where traditional patterns often fall short. Engineered for high-performance nymphing, this pattern features a heavy tungsten bead combined with a slim but weighted body, ensuring rapid descent into the strike zone. The black color profile makes it particularly effective in low-light conditions or during spring runoff when water is tinted and fish are feeding aggressively near the bottom.

This fly’s namesake “flexy” construction includes a flexible, anatomically accurate body and realistic leg movement that replicates the natural crawling and tumbling of a stonefly nymph. Segmented synthetic materials mimic the plated exoskeletons of real insects, while the use of a barbless jig hook keeps the fly riding point-up—reducing snags and improving hook-up ratios. It’s a favorite among tightline nymphers and Euro-style anglers who require a fly that delivers control, depth, and lifelike presentation.

Whether used as a point fly in a tandem rig or drifted solo through deep glides, the Flexy Stone is a confidence pattern in both freestone and tailwater environments. It consistently pulls attention from fish that are hugging the bottom, making it indispensable during early season fishing and high water periods when stonefly nymphs are on the move.Read More +
