Our new predator flies are available in several different colors and are made of light but strong synthetic material that can withstand sharp teeth and heavy use. They are designed and approved by Danish Brian Peter Størup and we only use original material from FutureFly. Due to the properties of the materials, it does not absorb water but releases it immediately when you start casting. The flies have good volume and profile but are still easy to cast, right down to a rod in class # 7 if you wish. The predator flies are about 20 centimeters long and tied on a hook of size 4/0. Sunny Day Predator # 4/0 is a color that fits perfectly fine days with clear water when you want a discreet fly that can attract even shy fish.
