Rock Hard Rainbow Trout


RealSwim Technology for a true swimming action.

SKU: N/A Categories: ,


nother of Castaic’s earliest and best-selling swimbaits, the Rock Hard Rainbow Trout is a beast. Triple-jointed with a durable hard body, the Rock Hard lives up to its name.

RealSwim Technology provides the most authentic swimming action possible. Available in 4″, 6″, 8″, and 10″ sizes and at varying weights and sink speeds.

The hand-painted body is resin-based. The results are an impressive, realistic hard body with the same great S-shaped swimming pattern you expect.

The Rock Hard is easy to fish at any speed. It’s not as sensitive as soft swim baits, but a lighter-than-you’d-expect body makes them easier to throw and retrieve.

The Rock Hard can even balance on the rear treble, like a real fish, giving you a darting action that entices even the most stubborn bass.
