The Win & Win Wiawis One is new concept limb that combines advanced manufacturing technology and Flaxpreg with eco-friendly natural materials. Flaxpreg is made of natural fibers and epoxy resins. This material has never been used in archery manufacturing before. Flaxpreg is environment-friendly material, and its twisted structure enhances the vibration damping effect in shooting. Win & Win applied high strength and high modulus carbon fiber to the limbs for the first time. Using Nano carbon, which is much stronger and has greater vibration absorption qualities than carbon fiber, has upgraded the bow technology and performance.
